description: next rejects promise when `this` value not an object
info: |
AsyncGenerator.prototype.next ( value )
1. Let generator be the this value.
2. Let completion be NormalCompletion(value).
3. Return ! AsyncGeneratorEnqueue(generator, completion).
AsyncGeneratorEnqueue ( generator, completion )
...
3. If Type(generator) is not Object, or if generator does not have an
[[AsyncGeneratorState]] internal slot, then
a. Let badGeneratorError be a newly created TypeError object.
b. Perform ! Call(promiseCapability.[[Reject]], undefined, « badGeneratorError »).
c. Return promiseCapability.[[Promise]].
