Hello,
the idea is to have different monads for I/O on different
resources. A simple
example is to have the two monads WorldIO and FileIO and a type
FileIOHandle.
A file is a part of the world. You have the following
functions:

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

Well, I'm a bit confused about your message, but the commands that you

doesn't sound like what you're trying to do.
You probably want "make register", which is what the readme file
recommends for installation.
