I am a haskell beginner and wondering how the following function works (in procedure) : oddsFrom3 :: [Integer] oddsFrom3 = 3 : map (+2) oddsFrom3 Thanks for your help. -- A GNU [1] LINUX [2] Patron Links: ------ [1] http://gnu.org [2] http://www.linuxfoundation.org/

Try to expand a few steps of the recursion by hand e.g.: 3 : (map (+2) (3 : map (+2) (3 : map (+2) ...))) As you can see, the deeper you go more 'map (+2)' are applied to '3'. Greetings, Daniel
