Standard Library: Iterator (std/iter.zc)

Use std/iter.zc to define custom iterators compatible with for-in loops. By implementing the Iterable trait, your types can integrate seamlessly with Zen C's loop syntax.

Usage

import "std/iter.zc"

// Assuming Mycollection implements Iterable<T>
for item in my_collection {
    // ...
}
