I'm trying to extend the asyncio REPL (yes, I know this is an unsupported use case) by doing the following:

• from asyncio.__main__ import AsyncIOInteractiveConsole
• Copy the if __name__ == '__main__' block into my own __main__.py
• Copy and edit REPLThread (subclassing isn't possible because it also refers to global variables)

However, this doesn't work because AsyncIOInteractiveConsole refers to asyncio.__main__'s global loop variable, despite it being passed and assigned to the instance attribute self.loop.

https://github.com/python/cpython/blob/3.13/Lib/asyncio/__main__.py#L65

I see no reason why AsyncIOInteractiveConsole shouldn't use self.loop consistently.
