What changed the internal [[Scope]] property in ES6?
I can find it in ES5, but not mention it in ES6.
It looks like it [[Scope]]was replaced by [[Environment]]in ES2015. Section 9.2.4 (FunctionInitialize) :
[[Scope]]
[[Environment]]
Set the internal span of [[Environment]] F to the scope.
while ES5 talks about this in section 13.2 (Creating Function Objects) :
Set the internal [[Scope]] F property for the scope value.
