It might be possible to get extremely fast code out of ghc, but as an overall impression, it's not easy, whilst Clean sort of gives it for granted (well, struggeling with wrongly assigned uniqueness attributes aside).

programs generated by ghc generally need multiples of time and space of the Clean version, even though the latter is, in many cases, a nearly literal translation from Haskell.
Maybe you'd be interested in Hacle? http://www-users.cs.york.ac.uk/~mfn/hacle/ " The aim was to develop a translator which is capable of reading in any given Haskell'98 program and writing out a semantically equivalent Clean one. Why? To investigate the suitability of the Clean compiler for compiling Haskell programs, i.e. Can the Clean compiler, in combination with this tool, produce faster executables than existing Haskell compilers?
