This LGTM!

I don't think I can see far enough ahead on what you are planning here, but I was just wondering if the ultimate goal is to  have the `option_arg.getAsT` return an `Expected<T>`. In this case, wouldn't all these arguments (short option, long option, additional context) have to be part of the interface of `getAsT`?  I suspect this is not your goal, but I can't see a way around that
