Thanks Albert, I believe that's the second time you've helped me this
weekend. I'm meiji11 in #haskell.
Cheers.

Haskell's laziness is tricky to understand coming from imperative
languages, but once you figure out its evaluation rules, you'll begin to
see the elegance.
Is there a paper or other single resource that will help me thoroughly
understand non-strictness in Haskell? Once my programs hit a

If performance is utterly vital the best resource is Core, as in, the
ability to read it. The order of
Why do you want to incrementally update this list a lot of times?
The question would affect the answer you get; i.e. some context
(non-monadically speaking). :D

The problem is that you build of a huge chain of updates to the

do this.
Are you using the right data structure for the job? Maybe you want an array
instead?
