System imports can be overriden by user-space files such as `queue.py`

[VorontsovIE]

Sometimes I run jupyter notebooks from Downloads folder (or from Telegram Downloads). Typically in this folder there are dozens of python files from my students and some are named smth like queue.py.

When I open a notepad located in a folder having such files, import queue under the hood of jupyter loads these files instead of system library queue. And of course, everything crashes. I added a log-trace below.

Indeed I know how to deal with such a problem, usually I just rename my queue.py into smth different so that python can choose stdlib version. But it can be embarassing for people who see it for the first time.

Probably it's possible to use importlib machinery not to override system imports with user-space python files?
