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").
