Per our discussion yesterday, I like this notion in general. (Seems we
need a better term for it, though, as "pattern matching" is very generic -
plus will confuse some people who'll think it refers to NIDS rules rather
than generic type safety!)

Personally, this strike me as a tad weird, since now "result" might not
have a statically determined type, so we're back to it being "any".
So I'd want to wait on going this far until we have use cases where
it clearly would help with code clarity.
