Ralf,
I'm a bit snowed under at the moment with the POPL PC meeting, but I'm
quite open to changing GHC's deriving behaviour. It's not hard to
change. The hard thing is figuring out just what the specification
should be.
So if you and others are able to evolve a better design, I'd be happy to

Function application is left-associative, so you can save parentheses.

GHC's profiler tries to overlay a lexical call graph on to the
dynamic execution of the program. It does this more or less in the
way you described before: every function gets an

In Haskell, code is data too because code in the sense of imperative
actions is described by IO values. You cannot analyse them. But you can
use your do expressions etc. to construct action descriptions with a more

Yeah! I've been struggling on concatMap for a noon and now here is the solution
