I think that should be amended to "just use hasattr(obj. '__call__')
instead". That's what callable() will become equivalent to once
old_style classes are gone.

Then it becomes a matter of whether it's worth having callable()
around as an alternative spelling. Those arguing in favour of
it would have to explain whether we should also have addable(),
subtractable(), mutiplyable(), indexable(), etc. etc. etc...
