Iterable interface

The inteface which requires iterator to be implemented:

fun iterator(): Iterator

Iterator itself is a simple interface that should provide only to method:

interface Iterable {
    fun hasNext(): Bool
    fun next(): Obj
}

Just remember at this stage typed declarations are not yet supported.

Having Iterable in base classes allows to use it in for loop. Also, each Iterable has some utility functions available:

toList()

Creates a list by iterating to the end. So, the Iterator should be finite to be used with it.

Included in interfaces:

• Collection, Array, List

Implemented in classes:

• List, Range
