Hi, Excuse the newbie'ness of my question. Saw an example in Two Dozen Questions by Rexx Page. blocks blockSize = takeWhile ( not . null ) . map fst . iterate (splitAt blockSize . snd) . splitAt blockSize What is the meaning of the . operators outside the parentheses ? Thsi does not look like function composition to me. Thanks, Anuj. The information contained in this message is proprietary of Amdocs, protected from disclosure, and may be privileged.
