By the way, you don't need the "flip" function. map (** 3) [0,1..10] [ x ** 3 | x <- [0,1..10]] The section (** 3) will figure out on which side to put the argument/operand. See http://www.haskell.org/haskellwiki/Section_of_an_infix_operator 2011/5/19 <jianqiuchi@gmail.com>:
OK, I see. Thanks a lot.
