Support named positional arguments

[nacl]

Hello!

Clingon looks rather nice. Looking through it, I wonder if there's support for what python's argparse calls "positional arguments". That is, arguments on the command line that are not associated with options, but are still accessible by a given name after arguments are processed.

For example, say I wanted to be able to access the first two named arguments as "foo" and "bar". If the user passes in:

$ cmd first second

A function like:

(getopt cmd 'bar)

should return "second".

Does clingon support this? I didn't see anything when I browsed the documentation and examples.

While it is possible to process the free arguments list to extract these arguments, it would be much simpler for the user if clingon could deal with it implicitly and provide all the nice machinery it provides for free.

Hey @nacl ,

Currently this behaviour is not supported in clingon. If I find some spare time I might be able to look into implementing it, but I'd also be happy to review any PRs!

Thanks!

Would also like to see this being implemented! :)
