The optimizer already changes semantic. Non-optimized "if a and True:" would call bool(a) twice, but optimized code calls it only once.
I don't understand this. Why would bool(a) be called twice, and when did this change? Surely calling it twice would be a bug.
I just tried the oldest Python 3 I have on this computer, 3.2, and bool is only called once.
