I'd rather argparse (or any library function) didn't call sys.exit on my behalf - it should raise an exception. Actually, sys.exit() does raise an exception (i.e. SystemExit) that you can catch if you want.

I was going to mention that. Between catching SystemExit, the '-i' switch to the interpeter and the PYTHONINSPECT environment variable, investigating applications that call sys.exit isn't that difficult. It's a far cry from the instant exits of a C level abort call.

Cheers, Nick.
