[New-bugs-announce] [issue20624] Clarify recommendation to inherit from Exception
report at bugs.python.org

New submission from Mark Dickinson:
"... programmers are encouraged to at least derive new exceptions from the Exception class and not BaseException."
This wording had someone I've talked to recently thinking that user-defined exceptions should inherit *directly* from Exception.
Suggested rewording, dropping the "at least" qualification that as far as I can tell serves no real purpose:
"... programmers are encouraged to derive new exceptions from the Exception class or one of its subclasses, and not from BaseException."
