.f -> .bin

Time to define the purrr18 language, which assembles straight to
binary. Maybe target-word structures should have a 'bin' slot?

ok.. now for assembling on the spot.  or is that not a good idea?

(assemble! (apply append (map cdr *code*)))

maybe it's time to start doing the "load in namespace" thing?
