can this support more than 26 options?

can this support more than 26 options? I.E. the limit of possibilities for the -short option, does that take anything other than alphas?

Looks like casing doubles that, plus you can use numbers, i.e.

short=P
short=p
short=1
short=9

I hadn't considered the case when you would run out of labels for the short flag. The short flag option can be made optional, would that work?
