Thanks! I'll work a little more on the swedish place name generator now
and post it soon.

Have you thought about a rule called "replace", that works similar to
reject, but instead of rejecting, it replaces? For example:

(mainpart (replace preliminary-mainpart (hh h) (rrr rr)))

This would fix "Southhall" and "Norrryd".
