I don't know if you're referring to the API or the implementation. But 
if you're referring to the API I think something like this could be made 
to work:

string outputFile;
getopt(args, "output", &outputFile).min(2).max(4).restrict("a", "b", 
"c", "d");

The current API stays exactly the same, it's just extended. This assumes 
it's possible to call "getopt" multiple times and you setup one argument 
per call, unless you want the same restrictions for multiple arguments.
