[New-bugs-announce] [issue20379] help(bound_builtin_class) does not display self

[Larry Hastings]

New submission from Larry Hastings:

For an object O that are bound to something (either a class or an instance), help(O) traditionally shows the bound argument.  For this code:

    class C:
        def foo(self, a):  pass

    c = C()

help(c.foo) would show the signature as "(self, a)", even though self has been bound.

My recent changes to Python's type system (#20189), to add inspect.Signature support for builtins, broke this.  The previous behavior should be restored.
