FWIW, + is inlined if it actually gets fixnums, so you don't have to
use fx+. It is just that fx+ can help you stay in the fast path by
giving you an error when you leave it (and unsafe-fx+ is a little bit

In general, I think the path forward will probably depend on
applications. That is, if you have some program that you care about
(not a toy) that can benefit from parallelism but won't work because
some operations are missing, then I expect they'll get added.
Otherwise, probably not.
