  1. data ((a :: Predicate k) &&& (b :: Predicate k)) (c :: TyFun k Type)

    decidable Data.Type.Predicate.Logic

    p &&& q is a predicate that both p and q are true.

  2. (&&) :: Bool -> Bool -> Bool

    dimensional Numeric.Units.Dimensional.Prelude

    Boolean "and", lazy in the second argument

  3. (&&) :: Bool -> Bool -> Bool

    distribution-opensuse OpenSuse.Prelude

    Boolean "and", lazy in the second argument

  4. (&&^) :: Monad m => m Bool -> m Bool -> m Bool

    distribution-opensuse OpenSuse.Prelude

    The lazy && operator lifted to a monad. If the first argument evaluates to False the second argument will not be evaluated.

    Just False &&^ undefined  == Just False
    Just True  &&^ Just True  == Just True
    Just True  &&^ Just False == Just False
    

  5. (&&&) :: Arrow a => a b c -> a b c' -> a b (c, c')

    dunai Data.MonadicStreamFunction.Core

    Fanout: send the input to both argument arrows and combine their output. The default definition may be overridden with a more efficient version if desired.

  6. (&|&) :: forall (m :: Type -> Type) a b c . Monad m => MSF m a b -> MSF m a c -> MSF m a (b, c)

    dunai Data.MonadicStreamFunction.Parallel

    Parallel version of &&&.

  7. (&&) :: Boolean b => b -> b -> b

    ersatz Ersatz.Bit

    Logical conjunction.

  8. (&&) :: Bool -> Bool -> Bool

    faktory Faktory.Prelude

    Boolean "and", lazy in the second argument

  9. type (p :: k) && (q :: k1) = And p q

    gdp Logic.Propositional

    An infix alias for And.

  10. (&.) :: GTraversal c a b -> Walk c b d -> GTraversal c a d

    greskell Data.Greskell

    Apply the Walk to the GTraversal. In Gremlin, this means calling a chain of methods on the Traversal object.
