I may have missed it in this thread, but if not, why didn't anyone suggest:
trans [] = [] trans [x] = [x] trans ('a':_:xs) = 'a' : 'A' : trans xs trans (x:xs) = x : trans xs
While as a beginner (I still am !) I would come up with a solution like this one, on the long run it helps trying to solve those problem with maps, folds, filters, and zips: Eventually, you'll find the code more readable, easier to write, and there's perhaps a better chance that it can be optimised by ghc.
