Are you shure about this? And why are you shure?
You put the blame on me for the bad performance of my code, and i can let
this
hold - i don't think that i am a haskell performance expert (though i am
learning
a lot through you people - thanks a lot).

But i want to know if it is just _theoretically_ possible or really easily
feasible.

See, i know of some C++ hackers who will eventually have to change to
Haskell.
This will get hard for them, and i don't know if they can get into complex
performance issues right from the start :-)

But i guess the C++ / Haskell comparison will look far better for Haskell
when
changing to computations with large data structures.
All i can tell by now is that Haskell works fine for me while C++ is ...
hard to program.
