[issue29114] __class__ not exists in the method which bounded by types.MethodType.

[Nick Coghlan]

Nick Coghlan added the comment:

Sorry, I wasn't at all clear about that part - the above techniques should work with explicitly created types.MethodType instances as well.

That is, this should work the same as in my earlier examples (although I don't have that interpreter session around to test it any more):

    >>> b = B()
    >>> b.fn = types.MethodType(make_B_method(), b)
    >>> b.fn()  # Emulated super()
    <class '__main__.A'>

If you were to build on top of what I wrote above (i.e. setting "B.fn = make_B_method()"), that explicit bound method creation would be akin to doing:

    >>> b = B()
    >>> b.fn = b.fn # Cache the bound method on the instance
