Prior to Python 3.7 we couldn't enable use of asynchronous generator expressions in synchronous functions:

    async arange(n):
        for i in range(n):
            yield i

    def make_arange(n):
        return (i async for i in arange(n))

(this is per PEP 530: https://www.python.org/dev/peps/pep-0530/#asynchronous-comprehensions)
