But that would be a behaviour change; is that desirable? E.g.,
Python 3.2a0 (py3k:74790, Sep 23 2009, 13:57:45)
[GCC 4.2.1 (SUSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class C:
... def __index__(self): return 3
... def __eq__(self, other): return True
...
>>> C() in range(0, 10, 2)
True
(Strictly speaking, I guess this patch is already a behaviour change for
subclasses of int that override __eq__ in weird ways).
