<DIV><FONT face=Arial size=2>OK, thanks for the references. I think I've got a
better handle on what's what. The library documentation mentions the ability to
convert the ST monad into an IO monad. What are the reasons/pluses/minuses of
doing this? (I can see one reason being that you won't have to use monad
transformers to try and thread two different monads through your
code).</FONT></DIV>

<DIV><FONT face=Arial size=2>Also, I didn't see any mention of a mutable List -
I suppose you have to use Data.Array.ST?</FONT></DIV>
