[issue38955] Non indemnpotent behavior of asyncio.get_event_loop and asyncio.run sequence.

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

Asyncio has a few own exceptions, the library tries to utilize existing ones, e.g. ValueError, TypeError, and OSError family. RuntimeError falls into this category.

get_event_loop() never returns None, it was from very beginning. If we change it existing third-party code will be broken. So, no way, sorry.

I really don't think we can change anything here.

Would you describe cases when you need an implicit loop instance but there is no running loop currently?
