Uncurried functions

Due to JavaScript's dynamic nature, BuckleScript cannot always optimize the compiled output to remove the intermediate functions. However, you can tell BuckleScript to uncurry a function using the following syntax:

let add = (. a, b) => a + b;

The uncurry syntax is the dot in the argument list. It needs to be present at both the declaration and call sites:

let result = add(. 2, 3); /* 5 */

BuckleScript will throw a compile time error if the call site isn't using the uncurry syntax:

let result = add(2, 3);We've found a bug for you!This is an uncurried BuckleScript function. It must be applied with a dot.Like this: foo(. a, b)Not like this: foo(a, b)

Also, a compile time error is thrown if some of the function's arguments ...
