Spread/splat operator nonfunctional in arrow functions

• Version: v5.11.0
• Platform: MSYS_NT-6.3
• Subsystem: --

Using this code:

"use strict";
let f = (...a) => a;
console.log(f(3, 4, 5));

I get this error:

let f = (...a) => a;
         ^^^

SyntaxError: Unexpected token ...

Whereas the expected output would be an array [3, 4, 5].

I don't think this was implemented in v8 until node v6.0.0, so you'll need to upgrade to get that feature.

Updating node to the latest version fixed the problem. Thanks!
