No, reverse returns a list. When you assign that list to a hash, you coerce that list *into* a hash. Without that explicit coercion, you'll get an error.

This works: 

    print keys %{ { reverse %hash } };

but it's way ugly, and it's probably slower, since it takes an anonymous hash ref to the list returned by reverse, then dereferences that hash ref into a hash.
