[issue20189] inspect.Signature doesn't recognize all builtin types

[Nick Coghlan]

Nick Coghlan added the comment:

It doesn't act like a class method, though, it acts like a static method:

    >>> int.__new__()
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: int.__new__(): not enough arguments
    >>> int.__new__(int)
    0

You have to *write* __new__ and tp_new as if they were class methods (because the type machinery expects you to do so), but you have to *call* them like static methods if you're invoking them directly for some reason.
