I think you can come a long way with the debugger in GHC HEAD. It provides a :trace command that, when applied to an expression with some breakpoint in it, remembers the history of evaluation steps. You can view the history with :hist. See: http://www.haskell.org/ghc/dist/current/docs/users_guide/ghci-debugger.html#... regards, Bas
