Of course we could, we'd "just" have to change a structure and
zend_verify_arg_class_kind() and of course the language syntax to allow
something like "function foo(A|B $bar) {}" but this still would mean to
break source compatibility in a bad way here as the user's code would
have to follow the signature and won't be able to be 5.2 and 5.3
compatible in one file.
