I need a Monad to represent an internal stack. I mean I've got a lot of functions which operates on lists and I would not like to pass the list as an argument everytime.
Could you help me writing this monad? To start, I just need a + function which will return the sum of the 2 toppest elements of the stack. Thanks in advance, Sam. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
