I hate to pull out the bikeshed paint... But why not!

I'm not sure actually. I often leave one argument off the end of a function.
I don't think that's too unlikely.

Ah, I think I know what I really want here.

If the arguments that are specified match the parameters, but there simply
aren't enough or is one too many, I would rank that candidate before an
explicit argument mismatch.

If the arguments don't match the parameter types *and* there are too many or
not enough, I would rank that candidate after.

Is that feasible to implement?
