[Python-Dev] Constancy of None (original) (raw)

(And is it time to make assignments to True and False trigger a SyntaxWarning, or should that wait until 2.5?)

We should be much more conservative with that. There's tons of code out there that assigns these (conditionally, if it's 2.3-aware) to truth values and we don't want to break that. The situation with None is much better, since it was always there; AFAIK only a few speed freaks in Zope-land have ever assigned to it (and always using the form "None = None").
