If you want a null function, just create one: def return_none(*_a, **_kw): pass What is your use-case for wanting NoneType to behave in this way? Is this yet another idea that actually has no use-case and is just "wouldn't it be nice if we did weird stuff to the language"? I'm starting to have to read python-ideas by first looking at the poster and only then consider the content of the suggestion, instead of what I usually prefer, which is to evaluate an idea on its merits regardless of who posted it.
it's not my own use case for once. the PEP clearly lists a use-case. we should support that use-case.
