Cannot find name 'Iterable' when including ES2015.Promise #37680
Description
I've been using Promises (and async) in ES5 with TypeScript.
It used to work fine in TypeScript 3.1
However, after upgrading to TypeScript 3.8.3, I consistently get this error:
Cannot find name 'Iterable'
this sucks.
I can include "ES2015.Iterable", but that doesn't solve the problem.
Some stackoverflow post suggest adding "ES2015.Symbol", but that doesn't help either.
I can also just create an empty test.ts file, and i still get this error, although there is no code at all.
This seems to be a TypeScript issue.
Apparently, I cannot add ES2015.Proxy without adding ES2016.
As soon as I add ES2016, the error goes away.
Problem is, I still need to support Internet Exploder, so I cannot just add ES2016 there, since IE doesn't support it. ES2015.Promise is really all I want, so that I can change the code to async already.
Please fix this annoying bug.
