Confirm parameter is one of list of Types

[StevenTCramer]

I have some code that takes a param that can be of TypeA or TypeB only. Not sure how to write a Guard for that.

Thanks!

Hi @StevenTCramer - unfortunately, we didn't have this support, and now I'm retiring Guard. I apologise for any inconvenience, and thank you for all the support. The readme has details.
