 				Returns the current iterable value. [param iter] stores the iteration state, but unlike [method _iter_init] and [method _iter_next] the state is supposed to be read-only, so there is no [Array] wrapper.
+				[b]Tip:[/b] In GDScript, you can use a subtype of [Variant] as the return type for [method _iter_get]. The specified type will be used to set the type of the iterator variable in [code]for[/code] loops, enhancing type safety.
