Add tests for lifted variables in async/iterator code #23929

Open gafter opened 6 years ago

gafter commented 6 years ago

We do not have many tests that verify the set of variables lifted in async or iterator code. It would be good to add a bit of testing infrastructure to make that easy, and add tests. Also, this could be added to the checklist for new features.

Functional tests do not work for this because extra lifted variables are not observable in the runtime behavior.
