Well, maybe I shoud be asking a higher level question then. I have a function tidy = reverse . dropWhile punk . reverse . dropWhile punk where punk = isPunctuation . chr . fromIntegral which is leading to a significant amount of allocation, and you can see why. The way I'd like to write it is tidy = dropWhile punk . dropWhileEnd punk where .... which has the obvious advantage of avoiding quite a bit of intermediate allocation. Is there a another way? I note that since I'm using a nice declarative language, the compiler CLEARLY should be transforming the first form into the second. :-) T. -- Dr Thomas Conway drtomc@gmail.com Silence is the perfectest herald of joy: I were but little happy, if I could say how much.
