- Object members are always allowed even on unknown types; non-Object members require explicit casts. Remove `inspect` from Object and use `toInspectString()` instead.
- Type expression checks: `x is T` is value instance check; `T1 is T2` is type-subset; `A in T` means `A` is subset of `T`; `==` is structural type equality.
- Type aliases: `type Name = TypeExpr` (generic allowed) expand to their underlying type expressions; no nominal distinctness.
- Bounds and variance: `T: A & B` / `T: A | B` for bounds; declaration-site variance with `out` / `in`.
- Do not reintroduce bytecode fallback opcodes (e.g., `GET_NAME`, `EVAL_*`, `CALL_FALLBACK`) or runtime name-resolution fallbacks; all symbol resolution must stay compile-time only.

## 1. Core Philosophy & Syntax
- **Everything is an Expression**: Blocks, `if`, `when`, `for`, `while`, `do-while` return their last expression (or `void`).
- **Static Types + Inference**: Every declaration has a compile-time type (explicit or inferred). Types are Kotlin‑style: non‑null by default, nullable with `?`.
- **Loops with `else`**: `for`, `while`, and `do-while` support an optional `else` block.
- `else` executes **only if** the loop finishes normally (without a `break`).
- `break <value>` exits the loop and sets its return value.

3. Result of the last iteration (if loop finished normally and no `else`).
4. `void` (if loop body never executed and no `else`).
- **Implicit Coroutines**: All functions are coroutines. No `async/await`. Use `launch { ... }` (returns `Deferred`) or `flow { ... }`.
- **Functions**: Use `fun` or the short form `fn`. Function declarations are expressions returning a callable.
- **Variables**: `val` (read-only), `var` (mutable). Supports late-init `val` in classes (must be assigned in `init` or body).
- **Serialization**: Use `@Transient` attribute before `val`/`var` or constructor parameters to exclude them from Lynon/JSON serialization. Transient fields are also ignored during `==` structural equality checks.
- **Null Safety**: `?` (nullable type), `?.` (safe access), `?( )` (safe invoke), `?{ }` (safe block invoke), `?[ ]` (safe index), `?:` or `??` (elvis), `?=` (assign-if-null).
@ -46,21 +44,9 @@ High-density specification for LLMs. Reference this for all Lyng code generation
- **Root Type**: Everything is an `Object` (root of the hierarchy).
- **Nullability**: Non-null by default (`T`), nullable with `T?`, `!!` asserts non-null.
- **Untyped params**: `fun foo(x)` -> `x: Object`, `fun foo(x?)` -> `x: Object?`.
- **Untyped vars**: `var x` is `Unset` until first assignment locks the type (including nullability).
- `val x = null` -> type `Null`; `var x = null` -> type `Object?`.
- **Inference**:
- List literals infer union element types; empty list defaults to `List<Object>` unless constrained.
- Map literals infer key/value types; empty map defaults to `Map<Object, Object>` unless constrained.
- Mixed numeric ops promote `Int` + `Real` to `Real`.
- **Type aliases**: `type Name = TypeExpr` (generic allowed). Aliases expand to their underlying type expressions (no nominal distinctness).
- **Generics**: Bounds with `T: A & B` or `T: A | B`; variance uses `out`/`in` (declaration‑site only).
- **Casts**: `as` is a runtime-checked cast; `as?` is safe-cast returning `null`. If the value is nullable, `as T` implies `!!`.
## 2.2 Type Expressions and Checks
- **Value checks**: `x is T` (runtime instance check).
- **Type checks**: `T1 is T2` and `A in T` are subset checks between type expressions (compile-time where possible).
- **Type equality**: `T1 == T2` is structural (unions/intersections are order‑insensitive).
- **Compile-time enforcement**: Bounds are checked at call sites; runtime checks only appear when the compile‑time type is too general.
- **Untyped vars**: `var x` is `Unset` until first assignment locks the type.
- **Inference**: List/map literals infer union element types; empty list is `List<Object>`, empty map is `{:}`.
- **Generics**: Bounds with `T: A & B` or `T: A | B`; variance uses `out`/`in`.
## 3. Delegation (`by`)
Unified model for `val`, `var`, and `fun`.

- Members must be marked `extern` so the compiler emits ABI slots for Kotlin bindings.
- You can also bind by name/module via `LyngObjectBridge.bind(...)`.

# `.lyng.d` Definition Files
`.lyng.d` files declare Lyng symbols for tooling without shipping runtime implementations. The IntelliJ IDEA plugin merges
all `*.lyng.d` files from the current directory and its parent directories into the active file’s analysis, enabling:
- completion
- navigation
- error checking for declared symbols
- Quick Docs for declarations defined in `.lyng.d`
Place `*.lyng.d` files next to the code they describe (or in a parent folder). The plugin will pick them up automatically.
## Writing `.lyng.d` Files
You can declare any language-level symbol in a `.lyng.d` file. Use doc comments before declarations to make Quick Docs
work in the IDE. The doc parser accepts standard comments (`/** ... */` or `// ...`) and supports tags like `@param`.
### Full Example
```lyng
/** Library entry point */
extern fun connect(url: String, timeoutMs: Int = 5000): Client
/** Type alias with generics */
type NameMap = Map<String, String>
/** Multiple inheritance via interfaces */
interface A { abstract fun a(): Int }
interface B { abstract fun b(): Int }
/** A concrete class implementing both */
class Multi(name: String) : A, B {
/** Public field */
val id: Int = 0
/** Mutable property with accessors */
var size: Int
get() = 0
set(v) { }
/** Instance method */
fun a(): Int = 1
fun b(): Int = 2
}
/** Nullable and dynamic types */
extern val dynValue: dynamic
extern var dynVar: dynamic?
/** Delegated property */
class LazyBox(val create) {
fun getValue(thisRef, name) = create()
}
val cached by LazyBox { 42 }
/** Delegated function */
object RpcDelegate {
fun invoke(thisRef, name, args...) = Unset
}
fun remoteCall by RpcDelegate
/** Singleton object */
object Settings {
val version: String = "1.0"
}
/** Class with documented members */
class Client {
/** Returns a greeting. */
fun greet(name: String): String = "hi " + name
}
```
See a runnable sample file in `docs/samples/definitions.lyng.d`.
Notes:
- Use real bodies if the declaration is not `extern` or `abstract`.
- If you need purely declarative stubs, prefer `extern` members (see `embedding.md`).
## Doc Comment Format
Doc comments are picked up when they immediately precede a declaration.
```lyng
/**
* A sample function.
* @param name user name
* @return greeting string
*/
fun greet(name: String): String = "hi " + name
```
## Generating `.lyng.d` Files
You can generate `.lyng.d` as part of your build. A common approach is to write a Gradle task that emits a file from a
template or a Kotlin data model.
Example (pseudo-code):
```kotlin
tasks.register("generateLyngDefs") {
doLast {
val out = file("src/main/lyng/api.lyng.d")
out.writeText(
"""
/** Generated API */
fun ping(): Int
""".trimIndent()
)
}
}
```
Place the generated file in your source tree, and the IDE will load it automatically.

### Closures inside coroutine helpers (launch/flow)
Closures executed by `launch { ... }` and `flow { ... }` use **compile‑time resolution** just like any other Lyng code:
Closures executed by `launch { ... }` and `flow { ... }` resolve names using the `ClosureScope` rules:
- **Captured locals are slots**: outer locals are resolved at compile time and captured as frame‑slot references, so they remain visible across suspension points.
- **Members are statically resolved**: member access requires a statically known receiver type or an explicit cast (except `Object` members).
- **No runtime fallbacks**: there is no dynamic name lookup or “search parent scopes” at runtime for missing symbols.
1. **Current frame locals and arguments**: Variables defined within the current closure execution.
2. **Captured lexical ancestry**: Outer local variables captured at the site where the closure was defined (the "lexical environment").
3. **Captured receiver members**: If the closure was defined within a class or explicitly bound to an object, it checks members of that object (`this`), following MRO and respecting visibility.
4. **Caller environment**: Falls back to the calling context (e.g., the caller's `this` or local variables).
5. **Global/Module fallbacks**: Final check for module-level constants and global functions.
Implications:
- Global helpers like `delay(ms)` and `yield()` must be imported/known at compile time.
- If you need dynamic access, use explicit helpers (e.g., `dynamic { ... }`) rather than relying on scope resolution.
- Outer locals (e.g., `counter`) stay visible across suspension points.
- Global helpers like `delay(ms)` and `yield()` are available from inside closures.
- If you write your own async helpers, execute user lambdas under `ClosureScope(callScope, capturedCreatorScope)` and avoid manual ancestry walking.

# Scopes and Closures: compile-time resolution
# Scopes and Closures: resolution and safety
Attention to AI: name lookup in runtime `Scope` is legacy. The bytecode compiler uses **compile-time name/member resolution only**.
Attention to AI: name lookup is ibsolete and must not be used with bytecode compiler
This page documents the **current** rules: static name resolution, closure captures, and the limited role of runtime `Scope` in Kotlin interop and explicit dynamic helpers.
This page documents how name resolution works with `ClosureScope`, how to avoid recursion pitfalls, and how to safely capture and execute callbacks that need access to outer locals.
## Current rules (bytecode compiler)
- **All names resolve at compile time**: locals, parameters, captures, members, imports, and module globals must be known when compiling. Missing symbols are compile-time errors.
- **No runtime fallbacks**: there is no dynamic name lookup, no fallback opcodes, and no “search parent scopes” at runtime for missing names.
- **Object members on unknown types only**: `toString`, `toInspectString`, `let`, `also`, `apply`, `run` are allowed on unknown types; all other members require a statically known receiver type or an explicit cast.
- **Closures capture slots**: lambdas and nested functions capture **frame slots** directly. Captures are resolved at compile time and compiled to slot references.
- **Scope is a reflection facade**: `Scope` is used only for Kotlin interop or explicit dynamic helpers. It must **not** be used for general symbol resolution in compiled Lyng code.
## Why this matters
Name lookup across nested scopes and closures can accidentally form recursive resolution paths or hide expected symbols (outer locals, module/global functions). The rules below ensure predictable resolution and prevent infinite recursion.
## Explicit dynamic access (opt-in only)
Dynamic name access is available only via explicit helpers (e.g., `dynamic { get { name -> ... } }`). It is **not** a fallback for normal member or variable access.
## Resolution order in ClosureScope
When evaluating an identifier `name` inside a closure, `ClosureScope.get(name)` resolves in this order:
## Legacy interpreter behavior (reference only)
The old runtime `Scope`-based resolution order (locals → captured → `this` → caller → globals) is obsolete for bytecode compilation. Keep it only for legacy interpreter paths and tooling that explicitly opts into it.
1. **Current frame locals and arguments**: Variables defined within the current closure execution.
2. **Captured lexical ancestry**: Outer local variables captured at the site where the closure was defined (the "lexical environment").
3. **Captured receiver members**: If the closure was defined within a class or explicitly bound to an object, it checks members of that object (`this`). This includes both instance fields/methods and class-level static members, following the MRO (C3) and respecting visibility rules (private members are only visible if the closure was defined in their class).
4. **Caller environment**: If not found lexically, it falls back to the calling context (e.g., the DSL's `this` or the caller's local variables).
5. **Global/Module fallbacks**: Final check for module-level constants and global functions.
This ensures that closures primarily interact with their defining environment (lexical capture) while still being able to participate in DSL-style calling contexts.
## Use raw‑chain helpers for ancestry walks
When authoring new scope types or advanced lookups, avoid calling virtual `get` while walking parents. Instead, use the non‑dispatch helpers on `Scope`:
- `chainLookupIgnoreClosure(name)`
- Walk raw `parent` chain and check only per‑frame locals/bindings/slots.
- Ignores overridden `get` (e.g., in `ClosureScope`). Cycle‑safe.
- `chainLookupWithMembers(name)`
- Like above, but after locals/bindings it also checks each frame’s `thisObj` members.
- Ignores overridden `get`. Cycle‑safe.
- `baseGetIgnoreClosure(name)`
- For the current frame only: check locals/bindings, then walk raw parents (locals/bindings), then fallback to this frame’s `thisObj` members.
These helpers avoid ping‑pong recursion and make structural cycles harmless (lookups terminate).
## Preventing structural cycles
- Don’t construct parent chains that can point back to a descendant.
- A debug‑time guard throws if assigning a parent would create a cycle; keep it enabled for development builds.
- Even with a cycle, chain helpers break out via a small `visited` set keyed by `frameId`.
## Capturing lexical environments for callbacks
For dynamic objects or custom builders, capture the creator’s lexical scope so callbacks can see outer locals/parameters:
1. Use `snapshotForClosure()` on the caller scope to capture locals/bindings/slots and parent.
2. Store this snapshot and run callbacks under `ClosureScope(callScope, captured)`.
Kotlin sketch:
```kotlin
val captured = scope.snapshotForClosure()
val execScope = ClosureScope(currentCallScope, captured)
callback.execute(execScope)
```
This ensures expressions like `contractName` used inside dynamic `get { name -> ... }` resolve to outer variables defined at the creation site.
## Closures in coroutines (launch/flow)
- The closure frame still prioritizes its own locals/args.
- Outer locals declared before suspension points remain visible through slot‑aware ancestry lookups.
- Global functions like `delay(ms)` and `yield()` are resolved via module/root fallbacks from within closures.
Tip: If a closure unexpectedly cannot see an outer local, check whether an intermediate runtime helper introduced an extra call frame; the built‑in lookup already traverses caller ancestry, so prefer the standard helpers rather than custom dispatch.
## Local variable references and missing symbols
- Unqualified identifier resolution first prefers locals/bindings/slots before falling back to `this` members.
- If neither locals nor members contain the symbol, missing field lookups map to `SymbolNotFound` (compatibility alias for `SymbolNotDefinedException`).
## Performance notes
- The `visited` sets used for cycle detection are tiny and short‑lived; in typical scripts the overhead is negligible.
- If profiling shows hotspots, consider limiting ancestry depth in your custom helpers or using small fixed arrays instead of hash sets—only for extremely hot code paths.
## Practical Example: `cached`
The `cached` function (defined in `lyng.stdlib`) is a classic example of using closures to maintain state. It wraps a builder into a zero-argument function that computes once and remembers the result:
```lyng
fun cached(builder) {
var calculated = false
var value = null
{ // This lambda captures `calculated`, `value`, and `builder`
if( !calculated ) {
value = builder()
calculated = true
}
value
}
}
```
Because Lyng now correctly isolates closures for each evaluation of a lambda literal, using `cached` inside a class instance works as expected: each instance maintains its own private `calculated` and `value` state, even if they share the same property declaration.
## Dos and Don’ts
- Do use `chainLookupIgnoreClosure` / `chainLookupWithMembers` for ancestry traversals.
- Do maintain the resolution order above for predictable behavior.
- Don’t call virtual `get` while walking parents; it risks recursion across scope types.
- Don’t attach instance scopes to transient/pool frames; bind to a stable parent scope instead.

- **Deep inference**: The compiler analyzes types of symbols along the execution path and in many cases eliminates unnecessary casts or type specifications.
- **Union and intersection types**: `A & B`, `A | B`.
- **Generics**: Generic types are first-class citizens with support for [bounds and variance](generics.md). Type params are erased by default and are reified only when needed (e.g., `T::class`, `T is ...`, `as T`, or in extern-facing APIs), which enables checks like `A in T` when `T` is reified.
- **Generics**: Generic types are first-class citizens with support for [bounds and variance](generics.md). No type erasure: in a generic function you can, for example, check `A in T`, where T is the generic type.
