And one could also set A=1 and B=1 if he was trying to be stupid. That
would fail the equality test and the identity test (in CPython). Seems
like this argument is getting a bit on the absurd side. The normal
idiom is to use equality checks to test state variables' *values*. I
don't know of any developer that would purposely try to break that when
defining a new module or class.
If Mark H wants to use an idiom that isn't conventional, or isn't widely
used, he is free to do so; I can't see much harm in it. But certainly
it's not the "normal" way that it's done in Python from what I can see.
