Given a function with a single argument as pair, returns its curried version

    sumPair : (Int, Int) -> Int -> Int
    sumPair (x, y) = x + y


    curriedSum : Int -> Int -> Int
    curriedSum x y = curry sumPair

Given a function with two (curried) arguments, returns a function whose only argument is a pair

    curriedSum : Int -> Int -> Int
    curriedSum x y = x + y


    sumPair : (Int, Int) -> Int -> Int
    sumPair = uncurry curriedSum

Flips the first two (curried) arguments of a function

    cons : a -> List a -> List a
    cons = (::)


    flippedCons : List a -> a -> List a
    flippedCons = flip cons

If function

    ifThenElse True "x" "_" -- => "x"
    ifThenElse False "_" "x" -- => "x"

Maps the value whether the given predicate holds true for that value

    showResults : List String -> List String
    showResults xs =
        xs
            |> ifThenMap List.isEmpty
                (\_ -> [ "Cannot find users matching this query" ])

Conditional if that can be used in update circuits to avoid parenthesis/anonymous functions eg.

    model
    |> doSomethingNiceWithModel
    |> ifThenElseMap someBooleanConditionBasedOnModel
        changeModelIfTrue
        changeModelIfFalse
    |> withoutCmds []
