show-0.4.1.2: 'Show' instances for Lambdabot

This package provides ShowQ, ShowFun, and SimpleReflect.

ShowFun gives us Typeable instances for neutering IO expressions.

ShowQ adds SmallCheck & QuickCheck support.

And SimpleReflect allows us to literally see how functions expand, through appropriate Show magic. See http://twan.home.fmf.nl/blog/haskell/simple-reflection-of-expressions.details.
