Ok but witness again:

L = [1, 2, Decimal("NaN"), 3] 3 in L True class H(object): ... def __eq__(self, other): raise ValueError ... L = [1, 2, H(), 3] 3 in L Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", line 2, in __eq__ ValueError

(NB: interestingly, float("nan") does hash) Regards Antoine.
