Question: About reference and instanceof

[Tofandel]

Should getIntrinsic output an object with the same reference as the original global?

So that new getIntrinsic('Map') instanceof Map would evaluate to true assuming Map wasn't modified?

I'm pretty sure yes, as It's currently the case in the package and the word "original" being used but might not be clear enough in this spec

Yes, absolutely it must; there's no other way it could work.

(the term you're looking for here is "identity", not "reference")
