Maybe. But there is more to it than just 'in'. If you do:
>>> c = numpy.zeros((2,))
>>> ll = [1, c, 3.]
then the following all throw errors:
3 in ll, 3 not in ll, ll.index(3), ll.count(3), ll.remove(3)
c in ll, c not i

Sorry
1) I was rude,
2) I thanked TJR for your wrapper class proposal in a later mail. It is
yours.

Dear All,
For the first time I have come across a Python feature that seems
completely wrong. After the introduction of rich comparisons, equality
comparison does not have to return a truth value, and may indeed return
nothing at all and throw an error instead. As a result, code like
if foo == b
10 matches
