(...) :: (a -> b) -> (b -> c) -> a -> c

ADPfusion - ADP.Fusion  

Applies the objective function h to a stream s. The objective function reduces the stream to a single optimal value (or some vector of co-optimal things).

lexp :: (a -> b) -> (b -> c) -> a -> c

pointless-haskell - Generics.Pointless.Combinators  

The left exponentiation combinator.

(|>) :: (a -> b) -> (b -> c) -> a -> c

hx - Haskell.X.Ops  

flip (.), fixity is infixl 9 (same as for .), from F#.

withCont :: ((b -> r) -> a -> r) -> Cont r a -> Cont r b

transformers - Control.Monad.Trans.Cont  

Apply a function to transform the continuation passed to a CPS computation.

withCont :: ((b -> r) -> a -> r) -> Cont r a -> Cont r b

mtl - Control.Monad.Cont  

Apply a function to transform the continuation passed to a CPS computation.

extQ :: (Typeable a, Typeable b) => (a -> q) -> (b -> q) -> a -> q

syb - Data.Generics.Aliases  

Extend a generic query by a type-specific case

mkQ :: (Typeable a, Typeable b) => r -> (b -> r) -> a -> r

syb - Data.Generics.Aliases  

Make a generic query; start from a type-specific case; return a constant otherwise

(#) :: (a -> b) -> (b -> c) -> a -> c

Animas - FRP.Animas.Miscellany  FRP.Animas  

Reverse composition

(<&>) :: (a -> b) -> (b -> c) -> a -> c

acme-cadre - Acme.Cadre  

(<&>) = flip (.). Hide this if you are importing <&> from Control.Lens.

queer :: (a -> b) -> (b -> c) -> a -> c

data-aviary - Data.Aviary.Birds  

Q combinator - queer bird.

Haskell (##) in Peter Thiemann's Wash, reverse composition.

queer :: (a -> b) -> (b -> c) -> a -> c

data-aviary - Data.Aviary.BirdsInter  

Q combinator - queer bird.

Haskell (##) in Peter Thiemann's Wash, reverse composition.

queer :: (r1 -> a) -> (a -> ans) -> r1 -> ans

data-aviary - Data.Aviary.BirdsVersion  

Q combinator - queer bird.

Haskell (##) in Peter Thiemann's Wash, reverse composition.

(>>>) :: (a -> b) -> (b -> c) -> a -> c

data-aviary - Data.Aviary.Functional  

For the function instance of Category left-to-right composition is the queer bird.
