There is something fishy going on with kwarg parsing. Namely, using something like:

@VCALL fx(a | int b = 0; int c = 0)

Will fail because there is no terminating semicolon. We need to at least throw an error. I think this is as simple as checking to make sure that the last semi-colon is also the end of the config here: https://github.com/leios/quibble/blob/main/src/quibble_args.c#L228.

I just need to think about it for a second.
