How do I use ES2015 Proxy in Meteor?

Question

Since Meteor 1.2 ES2015 is supported by default for any .js file in a Meteor project. That's great, but when I try to use the name Proxy like

const p = new Proxy(obj1, obj2);

it throws an undefined name Proxy.

I know ES6 is supported as all other features work (including Promises). So what am I doing wrong?

Just figured it out. Meteor uses Babel transpiler which doesn't offer support for Proxies, since it isn't possible to polyfill using ES5.

Did you do add the ecmascript package to your project?

meteor add ecmascript

It isn't native to 1.2; you still need to add it to your project.

Yeah, I did. Like I said, I use all other ES6 features, I just don't seem to be able to use that in particular. Maybe it's on a different name? I don't know, I can't find anything about it – Dec 14 '15 at 15:48
