The reason I'm feeling annoyed with ANYfoo stuff today is that yesterday
I had to put a special hack for ANYARRAY into the ri_triggers code,
which you'd think would have no concern with it. But perhaps this is
just an indication that we need to refactor the code in parse_coerce.c.
(The problem in ri_triggers is that it uses find_coercion_pathway()
which does not concern itself with ANYfoo types.)

Anyway, objection withdrawn --- I just thought it seemed a good idea to
question whether we were adding a frammish we didn't really need.
