Which reminds me about a proposal I made here last November:
http://mail.python.org/pipermail/python-dev/2001-November/018394.html
Executive summary: Make KeyboardInterrupt inherit directly from Exception
instead of from StandardError, so your standard idiom becomes:
try:
fragile code
except StandardError:
recover
Anything that you might generally not want to trap (KeyboardInterrupt and
SystemExit are the usual suspects, but Warning and StopIteration also fall
into this category I think) should not inherit from StandardError.
