better javascript/Node.js/es6 syntax highlighting

[xpepermint]

• VSCode Version: Code 1.3.1 (e6b4afa, 2016-07-12T13:31:10.994Z)
• OS Version: Darwin x64 15.5.0

Motivation
It seems that nobody deeply cares about Javascript/Nodejs syntax highlighting. VSCode does a better job then other text editors (e.g. Atom) but it's not perfect. VSC could be the #1 choise for javascript developers if some common syntax highlighting bugs were fixed.

Steps to Reproduce

Example 1:

let from = neki;
from = a; // is a variable and should be in white color like other variables

Example 2:

exports.myVar = async (ctx, next) => {} // this is all in white but exports and async should be e.g. in red or blue

Example 3:

t.me = 1;
t.is = 2; // `is` is in blue but should be the same color as the above (1)
t.in = 3; // `in` is in blue but should be the same color as the above (1)
t.of = 4; // `of` is in blue but should be the same color as the above (1)

I love vsc except the syntax highlighting part. It will be great to have this feature
