Is vars() the most useless Python built-in ever?

I found out about clize by developing my own module that did the same
job - and then found that, by compromising VERY slightly on some
specifics, I could turn my usage directly to clize :)

One thing I didn't want to compromise on was the simplicity of setup
that I'd had - just slap a decorator onto every function that you want
to make into a callable. So I made my own decorator that collects up
the functions. Total cost: Three lines at the top, two at the bottom
(if name is main, clize.run), and one line per function, plus the
encoded docstring. That's a LOT cheaper than argparse normally is.
