syntactic sugar improving 'assert' and 'error'; documentation

 This library contains syntactic sugar that improves
 the usability of 'assert' and 'error'.
 This is actually a bunch of hacks wrapping the original
 'assert' function.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
 See http://www.haskell.org/ for more information on Haskell.
