 See the `addFive` intermediate function? `add` takes in 3 arguments but received only 1. It's interpreted as "currying" the argument `5` and waiting for the next 2 arguments to be applied later on. Type signatures:
 
 ```resi
-let add: (int, int, int) => int;
-let addFive: (int, int) => int;
-let twelve: int;
+let add: (int, int, int) => int
+let addFive: (int, int) => int
+let twelve: int
 ```
 
 (In a dynamic language such as JS, currying would be dangerous, since accidentally forgetting to pass an argument doesn't error at compile time).
