The reason I ask is I am writing someting which will generate large case statements like the first form and want to know if I should bother pre-optimizing it to the second. John
I suppose such things should be made by flex-style generators. Haskell has one (called Happy); I wonder how efficient it is compared to hand-written "case .. of" or "if .. = .." scanners. I've heard flex is at least not worse than hand-written C code. -- Max
