Tuple definition

(=>) : a -> b -> ( a, b )

Define a double with infix operator. Primarily used, when defining a List with key-value Tuples.

Dict.fromList
    [ 0 => 'a'
    , 1 => 'b'
    , 2 => 'c'
    ]

map : (b -> x) -> ( a, b ) -> ( a, x )

mapFst : (a -> x) -> ( a, b ) -> ( x, b )

mapSnd : (b -> x) -> ( a, b ) -> ( a, x )

mapEach : (a -> x) -> (b -> x_) -> ( a, b ) -> ( x, x_ )

mapBoth : (a -> b) -> ( a, a ) -> ( b, b )

swap : ( a, b ) -> ( b, a )

sort : ( comparable, comparable ) -> ( comparable, comparable )

sortBy : (a -> comparable) -> ( a, a ) -> ( a, a )

sortWith : (a -> a -> Order) -> ( a, a ) -> ( a, a )

toList : ( a, a ) -> List a
