I don't know what lazyArray does, but i can guess from the name.
Beware that the ST monad in GHC (and I believe now Hugs too) is strict
in the state. This is contrary to the semantics described in the state
monad papers.
As a compromise between efficiency and semantic purity, both Hugs and GHC
now have a module "LazyST" that provides the "old-school" lazy state
monad semantics.

Hello.
I'm in the process of trying to port some code originally written for
hbc. This code uses lazyArray (among other things). I assume others
may have run into this before, but have not found mention of it in any
Haskell-related list archive. Basically, I'm wondering if anyone has
rolled their own lazyArray for any non-hbc compiler. I'd be interested
in any and all solutions people may have devised to implement/work
around lazyArray. Any leads? (Please reply directly to me,
[EMAIL PROTECTED], as well as to the lists.)
If I hear nothing, it will be time to start hacking. I'll do what I
can with requests of the form "me, too!"
