Double colon (::) operator

[flipjs]

I downloaded a boilerplate from TJ Holowaychuk and he is using :: operator like this ::this.onClick . I guess it has the same effect as this.onClick.bind(this).

My vim editor complains about this and the message is "Parsing error: Unexpected token : (undefined)" . Is this being added to standard? Or does eslint even support this yet?

Here's the link to TJ's code:

This is an ES7 feature. You need to use the custom parser, babel-eslint. See: http://standardjs.com/index.html#can-i-use-a-custom-js-parser-for-bleeding-edge-es6-or-es7-support
