[Haskell-cafe] Need some help with an infinite list

Hi guys, I'd like to generate an infinite list, like ["a", "b", "c" .. "z", "aa", "ab", "ac" .. "az", "ba", "bb", "bc" .. "bz", "ca" ...] When I had set out to do this I thought, oh yeah no prob, in a heartbeat. Uhm. Help, pls! Günther PS: I know this should be a no-brainer, sry
