You forgot to quote this bit:
4) Should we strive to eliminate non-Boolean operations on bools
in the future, through suitable warnings, so that for example
True+1 would eventually (in Python 3000) be illegal?
=> No.
There's a small but vocal minority that would prefer to see
"textbook" bools that don't support arithmetic operations at
all, but most reviewers agree with me that bools should always
allow arithmetic operations.
