9th Edition - ES.Next

Stage 3 (Candidate)
===================

1. SIMD - Single Instruction Multiple Data
	http://www.2ality.com/2013/12/simd-js.html

	https://github.com/tc39/ecmascript_simd/blob/master/tc39/SIMD-128%20TC-39.pdf

	In a nutshell: 
	Allows arithmetic and other operations on vectors of data simultaneously.

2. Function.prototype.toString revision
	http://tc39.github.io/Function-prototype-toString-revision/

	http://www.2ality.com/2016/08/function-prototype-tostring.html

	In a nutshell: 
	Requires Function.prototype.toString to work like it does in Chrome

3. Template Literal Revision
	https://tc39.github.io/proposal-template-literal-revision/

	Drop all syntactic restrictions related to escape sequences in tagged template literals to allow weird unicode and hex stuff that would otherwise be a SyntaxError.

	e.g. tagFunc`\unicode` throws right now, but won't after this change.
