I recently got this familiar error:

    builtins.TypeError: __init__() takes 1 positional argument but 2 were given

It was annoying that I didn't know which `__init__` method was under discussion. I wish that Python used the `__qualname__` of the function to show this error message (and maybe others?) so it'll show like this: 

    builtins.TypeError: FooBar.__init__() takes 1 positional argument but 2 were given

If I'm not mistaken, the implementation of this error is in getargs.c in the function vgetargs1_impl.
