Since the temporary object containing the result of the call "Elements.Get_Tag_Name (Child)" is not accessible anywhere else, the effect is the same.
But, perhaps in some implementations, the "renames" accesses that temporary object, which means the memory containing it must not be freed until Tag is out of scope. Perhaps it is even required. Any compiler specialist here?
