I see why you changed the Pragma data type, but I'm not sure I want to set things up that way. I think I'd prefer to have the Pragma type parse the pragma itself into command-line arguments, then pass those off to various pragmas (Discover, Version, and so on) to parse as desired, potentially using System.Console.GetOpt if needed.

I tried that at first but my problem was all the pragma code seemed so specific to Discover that I was not sure how to still get the context to the parser for Discover and the general context for Version.
