Re: [Haskell-cafe] Stack Overflow, tail recursion and CPS

Hello Neil, thanks, that did indeed work. I guess I shot myself in the foot a bit here ... Cause my real problem isn't actually with Map but with IxSet (from HAppS) which to my knowledge does not have some sort of strict insert function. Me trying to be really clever just used Map as a random example here quietly hoping to get confirmation for "Yes, CPS is the anwer to force evaluation here, keep digging in that direction boy", or a straight CPS solution which I then would just translate to my problem. Um ... Didn't work, you were to clever, thanks a bunch Neil :) Günther Am 14.01.2009, 18:32 Uhr, schrieb Neil Mitchell :

Hi

...

I have changed the insertion algo to use foldl to make it tail-recursive but still get a stack overflow as the "insert" remains lazy.

Try foldl' and insertWith' - that should work.

Thanks

Neil
