"""
Async helper function that are invalid syntax on Python 3.5 and below.

This code is best effort, and may have edge cases not behaving as expected. In
particular it contain a number of heuristics to detect whether code is
effectively async and need to run in an event loop or not.

Some constructs (like top-level `return`, or `yield`) are taken care of
explicitly to actually raise a SyntaxError and stay as close as possible to
Python semantics.
