Oh thanks, this is very nice and have been in my TODO list for a while
(but other stuffs had higher priority). Your comment mentions "trig
functions" and their inverse -- is there a reason why this can't be
extended to pair of functions which are one the inverse of each other
(e.g. exp/log)?

Thanks!
