Hello Ketil,

it depends entirely on how fast you need. so it's again changing the
topic - while i say that haskell is slow compared to other languages,
i don't say that it is slow for you or that you need sped at all. why
it's repeated again and again? why you don't write to Don what you
don't need speed when he wrote that haslkell is fast but wrote this to
me? :(

i don't think that omitting strictness declarations is a mistake :)

oh, can we stop saying about shootout? if you want to see speed of
pure haskell code, look at papers about fast arrays/strings - their
authors have measured that lazy lists are hundreds times slower than
idiomatic C code. is use of lazy lists counted as mistake too and
paper authors had too small haskell experience?
