Regardless of input, always return a constant value.

Helpful adapter for function that only offer updates when one really just wants to replace a value:

List.updateAt index (always item) list

Change the order of the arguments of a two argument function.

Negated functional if-then-else

Checks a condition and returns the respective value.

Allows writing more natural conditional atttributes, elements, etc:

div [] [ unless isLoggedIn (text "not logged in") (a [] [ text "logout" ]) ]
