New submission from Thomas Grainger <tagrain@gmail.com>:
demo:
import traceback
import io
async def foo():
yield 1
traceback.print_stack(file=io.StringIO())
yield 2
async def bar():
return [chunk async for chunk in foo()]
next(bar().__await__(), None)
print("working!")
Traceback (most recent call last):
