.|. and .&. are operators because they are made from symbol characters. Operators default to infixl 9 unless specified otherwise, so no infix declaration is needed. However, Data.Bits does have infix declarations for .&. and .|. : infixl 8 `shift`, `rotate`, `shiftL`, `shiftR`, `rotateL`, `rotateR` infixl 7 .&. infixl 6 `xor` infixl 5 .|. If you want to check the fixity of an operator, use :info in GHCi. Prelude Data.Bits> :i .|. class (Num a) => Bits a where ... (.|.) :: a -> a -> a ... -- Defined in Data.Bits infixl 5 .|. -- Dave Menendez <d...@zednenem.com> <http://www.eyrie.org/~zednenem/> _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
