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#tracing
