Actually the idea was to for example generate predicates in match.pd
format for things like vectorizer pattern recog (I've done this for a few,
need to search for (partial) patches on my disk), so they are supposed
to be externally visible.
Of course we might want to make that explicit in some way with
a (extern_match ...) [or by prefixing local ones with a '*' ...].
