Yeah, but cleaning that up globally in all our tests sounds like a recipe for disaster.  And I'm sure we'll also find some tests where we really *do* want to keep regexps alive across CHECK-LABELS.

I suppose we could have a filecheck mode that behaves as you describe, but that also sounds worse.

Also, if you don't want to list the used variables, you can match on [[@CLEAR:.*]].
