I see the point, but Decimal("NaN") does not hash:

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 "", line 1, in File "", line 2, in eq ValueError

(NB: interestingly, float("nan") does hash)

Antoine.
