[Haskell-cafe] ANNOUNCE: pretty-tree

Iavor's pretty-show package is quite handy for these kind of tasks as well.
Highly recommended: http://hackage.haskell.org/package/pretty-show

Since Iavor package is not tree-centric, it'll probably not generate as
nice output as you can for real tree-like-data. However, since it works on
arbitrary Show instances, it's much more readily usable: It's (almost) a
drop-in replacement for show. I find it to be extremely valuable in
debugging tasks.
