You are right. It's more cosmetic than actual. I basically said that from
Not as a direct complaint, no. It turns up more as a misunderstanding of
how 'and' and 'or' work or a misunderstanding why bool returns what it does
instead of what someone thinks it should, as in the thread that started
this last week. This addresses that in a subtle indirect way by redefining
bool as an operator. Weather or not it would actually improve the ease of
understanding how python uses and interacts with boolean types and
operators, I'm really not sure.
As far as performance gain, I was thinking that in combination with making
True and False constants, it might be greater. But it may very well not
be. Maybe sometime in the near future I will try to test just how much of
a difference it could make. In any case the making of True and False into
constants is still an open python 3k issue.
This was more exploratory and since nobody else jumped in and took it up,
it seems it would be un-popular as well. But it's here for the record in
