there is really no reason to suggest that the result of a boolean comparison operator might be negative! I suspect the reason tagToEnum# currently takes an Int# is because literals like 5# are Int#.

There's no reason to suggest that the result of a boolean comparison might be 3, yet `Word#` includes that value. I don't think `Int#` is any worse than `Word#` in including lots of impossible values, and furthermore there's a lot less friction to using `Int#` because everything else uses it. Just saying. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/6135#comment:37 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
