I've already explicitly rejected the claim that professional Haskell code should be written to aid beginning users. Again, that's what textbooks are for. And I was explicitly commenting on the claim that it was obvious, from any version posted thus far, what the function was supposed to do. Your suggested code hardly helps make the function's purpose clear; comments (or, better yet, tests, such as: prop_length = \ ns xn -> sum ns <= length xn ==> map length (takeList ns xn) == ns do a much better job of explaining purpose). jcc _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
