Every function that accepts two arguments can be converted in one that accepts one argument:

> String.repeat
<function> : Int -> String -> String

> String.repeat 4
<function> : String -> String

type alias MyType = Int → String → String mytrial: MyType mytrial n s = String.repeat n s mytrial 3 “abc”
