Bug report

Bug description:

Docstring of this method has following signature specification:

     PyDoc_STR("__prepare__($cls, name, bases, /, **kwds)\n"
               ...

It's wrong, the first argument should be $type (a class method). Because of this, the inspect.signature() fails to parse the __text_signature__ attribute for the method.
