I am new to haskell, but I find your assertions surprising, given  
that from my experience the really performance critical code is  
little, and the reset can be even interpreted.
As far as I know C/C++ or similar are not really that advanced with  
respect to whole program optimization (not much more than inlining).

I had the impression that haskell, until the shootout push, was not  
good at optimizing/had not optimized libraries for some common  
computational kernels, but now is in a much better shape (for ghc),  
and with Don is doing, hopefully it will stay so.

Can you corroborate a little more your points?
