I definitely think you should do this -- i.e. flip back -- the other one
is repeating a database entry.  Consulting this small database should be
cheap.  Again, if you really want to do it by the book, make the
database in Lisp symbols: use a separate obarray and 'intern-soft' (the
poor man's elisp equivalent to FIND-SYMBOL+package of proper civilized
Lisps).
