Util.DeepSeq

Module taken from Dean Harington's post to the Haskell mailing list on Fri, 17 Aug 2001.

URL is currently http://www.haskell.org/pipermail/haskell/2001-August/007712.html

This module provides deepSeq and $!! which correspond to seq and $! except that they try to evaluate everything in the argument. For example, if a list is provided, the whole list must be evaluated.

For purposes of Haddock, empty instance declarations with where have had the where deleted.
