[issue29681] getopt fails to handle option with missing value in middle of list

Martin Panter added the comment: It's not clear what you expected the behaviour to be. A function cannot both raise an exception and return a value. In any case, you are correct in saying "the next option, '-d', is taken as the argument." I do not think this is a bug. See

[issue29679] Add @contextlib.asynccontextmanager

Nick Coghlan added the comment: It's probably worth a python-dev discussion, but I personally draw the line at "Does this need to import 'asyncio'?". If it does, then that's a clear dependency inversion, and the functionality doesn't belong in a relatively low level module like contextlib.
