I just want to make one small point here encouraging people to try out
new 'mtl' libraries. There are lots of *new* monad libraries,
The new & improved mtl:
* monadLib
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/monadLib
As well as,
* mmtl http://hackage.haskell.org/cgi-bin/hackage-scripts/package/mmtl
* mtl-tf http://hackage.haskell.org/cgi-bin/hackage-scripts/package/mtl-tf
and the huge,
* category-extras
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/category-extras
'mtl' isn't magic in any way. it isn't distributed with ghc, so we can
let the (library) free market pick a winner.
Now, if the monadLib guys would advertise their work a bit more
effectively...
