I would have expected 'b' to be in that list.

I would have expected this to be a boolean indicating whether or not
the function accepts **kwargs.

Rather than args and all_args, I would perhaps have used something
more specific like required_positional_args and positional_args

Are you aware of PEP-362?
http://www.python.org/dev/peps/pep-0362/

I think that inspecting the arguments of a function is a relatively
uncommon thing to do, so I don't really have any problem with the fact
that all the code to do it is located in a special module (inspect).
