-Reflect.js is a pure JavaScript implementation of [Mozilla's Parser API](https://developer.mozilla.org/en/SpiderMonkey/Parser_API). It does not currently support Mozilla specific extentions such as `let`, generators, list comprehensions, patterns, E4X, etc. but may eventually support ones that are/become Harmony proposals.  *I'll probably add patterns next because those are pretty sweet.*

 Builders are also supported.
