[New-bugs-announce] [issue41427] howto/descriptor.rst unnecessarily mentions method.__class__

[Yonatan Goldschmidt]

New submission from Yonatan Goldschmidt <yon.goldschmidt at gmail.com>:

In Doc/howto/descriptor.rst:

    # Internally, the bound method stores the underlying function,
    # the bound instance, and the class of the bound instance.
    >>> d.f.__func__
    <function D.f at 0x1012e5ae8>
    >>> d.f.__self__
    <__main__.D object at 0x1012e1f98>
    >>> d.f.__class__
    <class 'method'>

The bound method (PyMethodObject) does not store "the class of the bound instance" - it only stores the "function" and "self".
d.f.__class__ is the class of the "method" type itself, not the class of d.f's instance (D from d = D())

I think this mention should be removed from the documentation?
