It's a "must be solved" problem for everyone who implements the core of
SRFI-44 *and* for everyone who wants to add a new collection to the

SRFI-44 doesn't let him do better for future collections, because it
doesn't specify how to add new collections to the existing set.

BTW, for personal reasons unrelated to SRFI-44, I may not be able to
participate much in the discussion for a few days.
