New submission from Mark Dickinson:
From http://docs.python.org/3.4/library/exceptions.html:
... 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
Éric Araujo added the comment:
In my reading “at least” means that exceptions should derive from Exception if
they don’t derive from a more specific subclass. IOW the same meaning as your
proposed wording, but less clear. +1 to your rewording.
