[Haskell-cafe] Using unboxed integers

I have x, y :: Int# I expect that x <=# y :: Bool but ghc 7.8 says Couldn't match expected type ‘Bool’ with actual type ‘Int#’ In the expression: x <=# y In an equation for ‘b’: b = x <=# y I have MagicHash and I've imported the right modules so that <=# is recognised as *something*, but at this point I'm baffled. I'm also not clear on how I can show an Int#.
