It sounds reasonable. However knowledge of how program performs in
micro-steps does not add up, so the benchmarks may wet up appetite for lunch
that does not come. I have pointed into such example - an astonishing and
unexplained underperformance of Haskell with all the profiling information
at hand.

I guess Haskell compilers are not particularly good at detecting specific
properties of a program and hence with optimizing it. This however shows up
with size so Donald's benchmarks cannot catch that out.

For this reason, undiagnosed and untreated, Haskell has been abandoned for
example in Algebraic Dynamic Programming, in spite of its unparallel
expressive power and a lot of hope. In ILP/IFP and GP it failed too.
