A value of 1# represents True and 0# represents False. For a more detailed description of motivation for this change, discussion of implementation details and benchmarking results please visit the wiki page: http://hackage.haskell.org/trac/ghc/wiki/PrimBool There's also some cleanup: whitespace fixes in files that were extensively edited in this patch and constant folding rules for Integer div and mod operators (which for some reason have been left out up till now). }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/6135#comment:82> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
