Just a quick thought.

     union Iterable {
         use array;
         use ArrayAccess;
         use Traversable;
     }

     function bla(Iterable $iterable) {
         foreach($iterable as $element) {}
     }

Primitives like string, float, bool or int are not allowed in union. 
Only classes, interfaces and array. I doesn't see any benefit in 
combining string with int or int with float in one union.

Do I overlook or missed anything?
