Not replicated.
Python 3.7.0a0 (default:cebc9c7ad195+, Feb 28 2017, 01:09:27)
[GCC 6.2.0 20161027] on linux
Traceback (most recent call last):
File "acrash.py", line 25, in <module>
loop.run_until_complete(main())
File "/usr/local/lib/python3.7/asyncio/base_events.py", line 465, in
run_until_complete
return future.result()
File "acrash.py", line 21, in main
1/0
ZeroDivisionError: division by zero
That's inserting 1/0 just before "await aenum()". Switching the order
of the lines also produces the expected result - delayed output, then
an exception that shows the crashing line.
