Hi
I didn't say I agree, I most certainly don't. What I meant with my comment was that a slowdown of 10x, just to preserve laziness, is perfect fuel for those who claim that laziness is good in theory but bad in practice.
A bad implementation of laziness will always be slower than a bad implementation of strictness - as we have strict CPU's. However, laziness gives you some really cool opportunities for deforestation and supercompilation - so at some point Haskell will overcome the performance penalty of laziness and start to reap the performance benefits - I think... Thanks Neil
