ES6: vulcanize + babel produces errors b/c of strict mode issue(s)

[ebidel]

Atm, building an element in ES6 classes requires a transpiler like babel to work x-browser. That workflow looks something like this:

1. vulcanize | cripser (to get separate output.js file)
2. babel output.js

The full command is below. BabelJS adds "use strict"; to the top of the transpiled output:

Unfortunately, this means JS errors, as parts of core 'use strict' and other parts do not.

Fix
Easiest fix is to get ride of this global, make it window.Polymer = {.... I've confirmed changing this one line in the transpiled output works!

vulcanize polymer.html --inline-script | crisper -h polymer.v.html -j polymer.v.b.js; babel --compact false polymer.v.b.js -o polymer.v.b.js
