-### Lazy Properties with `cached`
-
-When you want to define a property that is computed only once (on demand) and then remembered, use the built-in `cached` function. This is more efficient than a regular property with `get()` if the computation is expensive, as it avoids re-calculating the value on every access.
-
-```kotlin
-class DataService(val id: Int) {
-    // The lambda passed to cached is only executed once, the first time data() is called.
-    val data = cached {
-        println("Fetching data for " + id)

-        "Record " + id

-// No printing yet
-println(service.data()) // Prints "Fetching data for 42", then returns "Record 42"
-println(service.data()) // Returns "Record 42" immediately (no second fetch)
-```
-
-Note that `cached` returns a lambda, so you access the value by calling it like a method: `service.data()`. This is a powerful pattern for lazy-loading resources, caching results of database queries, or delaying expensive computations until they are truly needed.

-
-You can declare a `val` field without an immediate initializer if you provide an assignment for it within an `init` block or the class body. This is useful when the initial value depends on logic that cannot be expressed in a single expression.
-

-        result = transform(data)

-}
-```
-
-Key rules for late-init `val`:
-- **Compile-time Check**: The compiler ensures that every `val` declared without an initializer in a class body has at least one assignment within that class body (including `init` blocks). Failing to do so results in a syntax error.
-- **Write-Once**: A `val` can only be assigned once. Even if it was declared without an initializer, once it is assigned a value (e.g., in `init`), any subsequent assignment will throw an `IllegalAssignmentException`.
-- **Access before Initialization**: If you attempt to read a late-init `val` before it has been assigned (for example, by calling a method in `init` that reads the field before its assignment), it will hold a special `Unset` value. Using `Unset` for most operations (like arithmetic or method calls) will throw an `UnsetException`.
-- **No Extensions**: Extension properties do not support late initialization as they do not have per-instance storage. Extension `val`s must always have an initializer or a `get()` accessor.
-
-### The `Unset` singleton

-The `Unset` singleton represents a field that has been declared but not yet initialized. While it can be compared and converted to a string, most other operations on it are forbidden to prevent accidental use of uninitialized data.

-### Restricted Setter Visibility
-
-You can restrict the visibility of a `var` field's or property's setter by using `private set` or `protected set` modifiers. This allows the member to be publicly readable but only writable from within the class or its subclasses.
-
-#### On Fields
-
-```kotlin
-class SecretCounter {
-    var count = 0
-        private set // Can be read anywhere, but written only in SecretCounter
-        
-    fun increment() { count++ }
-}
-
-val c = SecretCounter()
-println(c.count) // OK
-c.count = 10     // Throws AccessException
-c.increment()    // OK
-```
-
-#### On Properties
-
-You can also apply restricted visibility to custom property setters:
-
-```kotlin
-class Person(private var _age: Int) {
-    var age
-        get() = _age
-        private set(v) { if (v >= 0) _age = v }
-}
-```
-
-#### Protected Setters and Inheritance
-
-A `protected set` allows subclasses to modify a field that is otherwise read-only to the public:
-
-```kotlin
-class Base {
-    var state = "initial"
-        protected set
-}
-
-class Derived : Base() {
-    fun changeState(newVal) {
-        state = newVal // OK: protected access from subclass
-    }
-}
-
-val d = Derived()
-println(d.state) // OK: "initial"
-d.changeState("updated")
-println(d.state) // OK: "updated"
-d.state = "bad"  // Throws AccessException: public write not allowed
-```
-
-### Key Rules and Limitations
-
-- **Only for `var`**: Restricted setter visibility cannot be used with `val` declarations, as they are inherently read-only. Attempting to use it with `val` results in a syntax error.
-- **Class Body Only**: These modifiers can only be used on members declared within the class body. They are not supported for primary constructor parameters.
-- **`private set`**: The setter is only accessible within the same class context (specifically, when `this` is an instance of that class).
-- **`protected set`**: The setter is accessible within the declaring class and all its transitive subclasses.
-- **Multiple Inheritance**: In MI scenarios, visibility is checked against the class that actually declared the member. Qualified access (e.g., `this@Base.field = value`) also respects restricted setter visibility.

 - 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:
-
-```kotlin
-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.

-## Lazy evaluation with `cached`
-
-Sometimes you have an expensive computation that you only want to perform if and when it is actually needed, and then remember (cache) the result for all future calls. Lyng provides the `cached(builder)` function for this purpose.
-
-It is extremely simple to use: you pass it a block (lambda) that performs the computation, and it returns a zero-argument function that manages the caching for you.
-
-### Basic Example
-
-```kotlin
-val expensive = cached {
-    println("Performing expensive calculation...")
-    2 + 2
-}
-
-println(expensive()) // Prints "Performing expensive calculation..." then "4"
-println(expensive()) // Prints only "4" (result is cached)
-```
-
-### Benefits and Simplicity
-
-1.  **Lazy Execution:** The code inside the `cached` block doesn't run until you actually call the resulting function.
-2.  **Automatic State Management:** You don't need to manually check if a value has been computed or store it in a separate variable.
-3.  **Closures and Class Support:** `cached` works perfectly with closures. If you use it inside a class, it will correctly capture the instance variables, and each instance will have its own independent cache.
-
-### Use Case: Lazy Properties in Classes
-
-This is the most common use case for `cached`. It allows you to define expensive "fields" that are only computed if someone actually uses them:
-
-```kotlin
-class User(val id: Int) {
-    // The details will be fetched only once, on demand
-    val details = cached {
-        println("Fetching details for user " + id)
-        // Db.query is a hypothetical example
-        Db.query("SELECT * FROM users WHERE id = " + id)
-    }
-}
-
-val u = User(101)
-// ... nothing happens yet ...
-val d = u.details() // Computation happens here
-val sameD = u.details() // Returns the same result immediately
-```

-# What's New in Lyng
-
-This document highlights the latest additions and improvements to the Lyng language and its ecosystem.
-
-## Language Features
-
-### Class Properties with Accessors
-Classes now support properties with custom `get()` and `set()` accessors. Properties in Lyng do **not** have automatic backing fields; they are pure accessors.
-
-```lyng
-class Person(private var _age: Int) {
-    // Read-only property
-    val ageCategory get() = if (_age < 18) "Minor" else "Adult"
-
-    // Read-write property
-    var age: Int
-        get() = _age
-        set(v) {
-            if (v >= 0) _age = v
-        }
-}
-```
-
-### Private and Protected Setters
-You can now restrict the visibility of a property's or field's setter using `private set` or `protected set`. This allows members to be publicly readable but only writable from within the declaring class or its subclasses.
-
-```lyng
-class Counter {
-    var count = 0
-        private set  // Field with private setter
-        
-    fun increment() { count++ }
-}
-
-class AdvancedCounter : Counter {
-    var totalOperations = 0
-        protected set // Settable here and in further subclasses
-}
-
-let c = Counter()
-c.increment() // OK
-// c.count = 10 // Error: setter is private
-```
-
-### Late-initialized `val` Fields
-`val` fields in classes can be declared without an immediate initializer, provided they are assigned exactly once. If accessed before initialization, they hold the special `Unset` singleton.
-
-```lyng
-class Service {
-    val logger
-    
-    fun check() {
-        if (logger == Unset) println("Not initialized yet")
-    }
-
-    init {
-        logger = Logger("Service")
-    }
-}
-```
-
-### Named Arguments and Named Splats
-Function calls now support named arguments using the `name: value` syntax. If the variable name matches the parameter name, you can use the `name:` shorthand.
-
-```lyng
-fun greet(name, greeting = "Hello") {
-    println("$greeting, $name!")
-}
-
-val name = "Alice"
-greet(name:)                  // Shorthand for greet(name: name)
-greet(greeting: "Hi", name: "Bob")
-
-let params = { name: "Charlie", greeting: "Hey")
-greet(...params)              // Named splat expansion
-```
-
-### Multiple Inheritance (MI)
-Lyng now supports multiple inheritance using the C3 Method Resolution Order (MRO). Use `this@Type` or casts for disambiguation.
-
-```lyng
-class A { fun foo() = "A" }
-class B { fun foo() = "B" }
-
-class Derived : A, B {
-    fun test() {
-        println(foo())              // Resolves to A.foo (leftmost)
-        println(this@B.foo())       // Qualified dispatch to B.foo
-    }
-}
-
-let d = Derived()
-println((d as B).foo())             // Disambiguation via cast
-```
-
-## Tooling and Infrastructure
-
-### CLI: Formatting Command
-A new `fmt` subcommand has been added to the Lyng CLI.
-
-```bash
-lyng fmt MyFile.lyng             # Print formatted code to stdout
-lyng fmt --in-place MyFile.lyng  # Format file in-place
-lyng fmt --check MyFile.lyng     # Check if file needs formatting
-```
-
-### IDEA Plugin: Autocompletion
-Experimental lightweight autocompletion is now available in the IntelliJ plugin. It features type-aware member suggestions and inheritance-aware completion.
-
-You can enable it in **Settings | Lyng Formatter | Enable Lyng autocompletion**.
