If use CSP (without `unsafe-eval`), both `new Function` and `eval` will be forbidden, so `eval` part is just dead code.
The only possibility `eval` part would run was `new Function('return this')()` return a falsy value, but it never possible as the spec (Is there any old engine violate this? Never heard about that.)
This pr also add `new` keyword to make the code a little bit explicit.
* refactor(eslint): Added no-unsed-vars, env specific .eslintrc's for buildin & hot
* This change allows for buildin to now be part of the lint test by addition of an extra .eslintrc file which extends existing but sets es6 to false
* Turned on no-unused-vars for eslint, and then removed all warnings from turning that feature on
* Was getting notified of errors in "quote" property in eslintrc, so changed to correct value from error to 2.
* beautify
* swap invalid eslint config val
