I have a problem with notifying all current subscribers and new subscribers about the closure of the queue and the reason. For example, I have a producer that reads messages from websocket or something else and send this to a queue, and several consumers (I do not know how many). If any exception occurred, then all current subscribers and subscribers which will be added later should know about this error. I tried to send an exception to a queue, but that did not help, because I have several consumers. Also, this will not protect new consumers. I propose to add a new close method with exc argument, which will throw an exception when calling the get method, and also throw an exception for all current _getters.

You should probably bring this up on the python-ideas mailing list.

How to do this?

The python-ideas is hosted at https://mail.python.org/mailman3/lists/python-ideas.python.org/, you can create an account and once it's validated you will be able to post a new message either using the web UI or by sending a mail directly to the list.

Thank you so much

This can be re-opened if the discussion on the list warrants it.
