Some issues:

1. "ghc -M" complains about multiply-defined "Main" modules.
entered as 

2. What's up with "Warning: orphan instances"?

3. I notice show for rationals now does "3%2" instead of "3 % 2". 
Probably better, though it does break one of my tests...

4. It looks like Data.FiniteMap has been renamed Data.Map, or something. 
There's no Data.Map at <http://haskell.org/haddock/libraries/>, do these need to be updated?

5. Apparently a bunch of stuff is in different pacakges, such as mtl. Is 
there documentation about what's in what package? Perhaps Haddock should 
show packages or something? I'm not yet familiar enough with Cabal to 
know what the best way of doing this is.
