Python's guarantee in this case goes no further than that it promises not to crash in C code. There's a rule in the language reference that says that all __dunder__ names are reserved for the implementation and they should only be used according to the documentation. So, indeed, it's not illegal, but you are not guaranteed that anything works, either. -- --Guido van Rossum (python.org/~guido)
