Cool, that's a neat trick I'd never have thought of. I think the 2 line
alternative might be a little more pythonic though, in terms of
readability & simplicity...

if callback:
    callback(result, *callback_args)

That could be because I'm not terribly au fait with the whole lambda
calculus thing though. What say those who are comfortable with it?
Obvious or oblique?
