If I write:

fromdecoratorimportFunctionMakerfm=FunctionMaker(lambdax:x)print(f'{fm.defaults=}')

then I see

fm.defaults=None

However, the stubs show:

andNone can't be assigned totuple[Any, ...]

@donBarbos sorry for the ping, I just saw that you worked on these stubs a few months ago. Can you tell if it's accurate thatdefaults should betuple[Any, ...] | None?

Theinspect docs also note:

defaults is an n-tuple of default argument values corresponding to the last n positional parameters, or None if there are no such defaults defined
