Good point. I dismissed reusing the matcher here because of performance
concerns -- setting up the match is expensive (in the constant-time sense but
still a lot of overhead). But, we're already using matching quite a lot so I
suspect it doesn't matter. Still, what about the reverse -- use this predicate
in the matcher, which is faster while still ensuring consistent results?
That said, what I really want is for the matcher logic to be made available
outside of the matcher framework -- I think `NamedDecl` should have the core
logic (parallel to `getQualifiedNameAsString`) and that could be used
elsewhere, including the matcher.
