is superior to strictness, or versa; I don't, either. But you do say it's good to be encouraged to use laziness more often. Why? You mention compositionality above as a possible reason, in reply to which, see above. Cheers, Tim -- Tim Chevalier * http://cs.pdx.edu/~tjc * Often in error, never

Re: [haskell-cafe] Monad and kinds

. Strictness analysis is an approximation to the problem of determining what parts of a program can be evaluated strictly without changing their meaning, because if we had a perfect solution to that problem, we could solve the halting problem.

}) = (:) (d ++ show k ++ ++ n ++ ++ (show vl)) Then your profiling report will tell you how much time/memory that particular call to foldWithKey uses. By the way, using foldl rather than foldl' or foldr is almost always a performance bug. Cheers, Tim -- Tim Chevalier * http://cs.pdx.edu/~tjc

here (foldl' I understand). Could you shed some light on that for me please? I meant the call to foldl in termToStr. There's a good explanation of this at: http://en.wikibooks.org/wiki/Haskell/Performance_Introduction (look for foldl). Cheers, Tim -- Tim Chevalier * http://cs.pdx.edu/~tjc

won't check that assumption for you. I don't know whether that has anything to do with the original question, though :-) Cheers, Tim -- Tim Chevalier * http://cs.pdx.edu/~tjc * Often in error, never in doubt If you don't understand the causes, it is impossible to come up with a solution. -- Joe
