--harmony_modules isn't working?

[tusharmath]

Following the documentation given here https://nodejs.org/en/docs/es6/

Sample Code

import {partial} from 'lodash'
console.log(partial)

command

node --harmony_modules  Javascript.js
/Users/tushar.mathur/Documents/Projects/temp/Javascript.js:1
(function (exports, require, module, __filename, __dirname) { import {partial} from 'lodash'
                                                              ^^^^^^

Same results here, also on OS X (also with strict mode).
However, I'm not sure it is expected to work - I'm still transforming with BabelJS.

I guess I tweeted too soon :'(

Yay! ES6 modules finally :) https://t.co/g9oKPYXEEw

modules are still in 'in progress' in v8 - so I'd withdraw that tweet anyway!

$ node --v8-options | grep 'in progress' 

[tusharmath]

Well, I wanted to experiment with them without using a transpiler which I finally could (Or can't).

See this comment: https://code.google.com/p/v8/issues/detail?id=1569#c29

V8 developers are currently waiting WHATWG loader spec to mature before completing the ES2015 module support.

Closing. As others point out, ES6 modules are not implemented in V8 yet. As a rule of thumb, if a feature is behind a flag, you can expect it to be half-baked or downright broken.

And by now what? Is import implemented in node.js 6.0?
