Luau's loop, with two additions. A name in the head may be a table or an array pattern, { x, y } or [ a, b ], which destructures each item on the do line, and where cond after the iterator skips the items the condition rejects, with the names in scope. for reads a Queue, a Heap, and an Iter of the std as it reads a table.
