To alleviate #5 for now.

as I said here all target browsers could have native Symbol / Reflect. we should just add some notes / caveats about one might need polyfills to use autobind decorator. we need babel to use this anyway. so it's possible that user of this decorator already uses core.js (or even harmony-reflect or other polyfill). also this dependancy should be definitely added to peerDependencies if it will be added though

Native support for Reflect is almost not existent at the moment. Not sure if we want to require it explicitly though...

What about progressive enhancement?

1. If Reflect is globally defined, then use it.
2. If not, then use Object.getOwnPropertyNames() and don't worry about symbols

@aldendaniels good suggestion, anybody wants to submit a PR?
