ES6 Modules Support

[d3x0r]

example code...

//------ main.js ------
import * as lib from 'lib';

console.log(lib.square(11)); // 121
console.log(lib.diag(4, 3)); // 5

//------ lib.js ------
export const sqrt = Math.sqrt;
export function square(x) {
    return x * x;
}
export function diag(x, y) {
    return sqrt(square(x) + square(y));
}

//------ main.js ------
import { square, diag } from 'lib';
console.log(square(11)); // 121
console.log(diag(4, 3)); // 5

Even with the flag --harmony_modules nodeJS fails....

M:\javascript\module-test>h:\dev2\nodejs\node --harmony_modules main.js
M:\javascript\module-test\main.js:2
import * as lib from 'lib';
^^^^^^

ES6 module support is not complete at this time. Dupe of #2760

Fortunately, current version of node report nonexistent harmony flags: bad option: --harmony_modules.
