- * The [Iterable] interface allows to get an [Iterator] out of an

- * This interface is used by the for-in construct to iterate over an
- * [Iterable] object.
- * The for-in construct takes an [Iterable] object at the right-hand
- * side, and calls its [iterator] method to get an [Iterator] on it.
- *
- * A user-defined class that implements the [Iterable] interface can
- * be used as the right-hand side of a for-in construct.
