[Haskell-cafe] lists of arbitrary depth

hello, iam really new to haskell, i want to define a function which takes as a parameter a list which can contain other lists, eg. [1,[2,3],[4,[5,6]]] how would i define a function that can iterate through the items so (in this example) iter1 = 1 iter2 = [2,3] iter3 = [4,[5,6]] ? ( can i do that without using the Tree data type? ) THANKS! -- View this message in context: http://old.nabble.com/lists-of-arbitrary-depth-tp29139641p29139641.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com.
