Possible to have 'choice' type arguments?

[gCardinal]

I'd like to have an argument for a command only allow a list of valid values. Exactly like this commander example. Is this something possible with nest-commander?

You could simulate this with a required option which will pretty much act like an argument, but come in through the options parameter instead.

I can look into how to add this functionality otherwise, but it will probably be a breaking change to make the current commander API line up better with nest-commander's API

I opted for a custom validator service on the string I receive, but your method would have also worked. That being said, it would be great to have the ability for more robust arguments in nest-commander!
