How do you know you don't or won't have the same need for stack?
i run my program with rather large datasets - it's happy with current 8m stack. i had problems with filterM function, though, and replaced it with my own, tail-recursive but probably less efficient implementation i know that real problems for my programs will be solved by adding "heap releasing" or, say, x64 support. are you have real problems with stack management? if not, isn't it better to allow ghc developers to solve real problems for me and other people? things will never be ideal from my own POV the only serious argument may be that current situation limits usability of some programming techniques (CPS?) which is able to increase programmer's productivity -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
