I like the idea of union types in general, but have always felt that a typehint of Traversable should accept arrays as a matter of course. The only thing such a typehint guarantees is that foreach will work (there are no methods defined that can be called directly), and an array meets that condition. The only difference I can see is in the passing / mutability behaviour of objects vs non-objects.
