[Haskell-cafe] complex state code

[Tim Newsham]

I'm working on some code where I have some complex state. This is the 
first time I've dealt with anything like this in haskell.  If anyone would 
review my code and let me know if there are ways I could do this better, 
cleaner, in a more idiomatic way, etc, I would greatly appreciate it.
