[issue25779] deadlock with asyncio+contextmanager+ExitStack

[Yury Selivanov]

Yury Selivanov added the comment:

Created another issue for the reprlib bug: issue 25781.  It appears we don't even need a generator:

    import reprlib

    try:
        raise RuntimeError
    except RuntimeError as ex:
        ex.__context__ = ex
        reprlib.repr(ex)

Closing this one with "not a bug".

----------
resolution:  -> not a bug
status: open -> closed
superseder:  -> infinite loop in reprlib
