Return first argument, ignoring second

Return second argument, ignoring first

Passes a single value to both arguments of binary function. eg: let double = warbler (+)

Can be used to flip the arguments of a binary function. eg: cardinal String.concat "a";"b" ","

String.concat: string -> string list -> string, but by using cardinal it changes to string list -> string -> string

Composition eg: bluebird f g = f . g

Composition where b takes two arguments eg: blackbird add1 ( * )

Composition where b takes three arguments eg: blunting add1 ( fun x y z -> x * y *z )

Composition with 3 functions eg: becard add1 add1 add1
