I am a newbie learning haskell. (First forum post.) I am wondering if there is a trick to get debugging information about functions out of the environment (which for me, for now, is ghci). In this example, *UnixTools> :t map (*) [1,2] map (*) [1,2] :: (Num a) => [a -> a] This is very nice, but I would *really* like to see something like *UnixTools> explodeLambda( map (*) [1,2] ) [(\x -> 1*x),(\x -> 2*x)] Yes, maybe I'm dreaming, but I would like haskell to reverse engineer / pretty print lambda expressions for me. (Note that: *UnixTools> map ($ 5 ) [(\x -> 1*x),(\x -> 2*x)] [5,10] *UnixTools> map ($ 5) ( map (*) [1..2] ) [5,10] So these expressions really are the same, only it could be argued that the first expression is in some sense easier to read if you are debugging something complex. ) I would like to have something like "Data::Dumper" from perl, but of course, on steroids. Is something like this possible, or be worked on? Or probably never going to happen?
