I thank Steve D'Aprano for pointing me to this real-life (although perhaps extreme) code example
https://github.com/Tinche/aiofiles/blob/master/aiofiles/threadpool/__init__.py#L17-L37 <code> def open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True, opener=None, *, loop=None, executor=None): return AiofilesContextManager(_open(file, mode=mode, buffering=buffering, encoding=encoding, errors=errors, newline=newline, closefd=closefd, opener=opener, loop=loop, executor=executor)) @asyncio.coroutine def _open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True, opener=None, *, loop=None, executor=None): """Open an asyncio file.""" if loop is None: loop = asyncio.get_event_loop() cb = partial(sync_open, file, mode=mode, buffering=buffering, encoding=encoding, errors=errors, newline=newline, closefd=closefd, opener=opener) f = yield from loop.run_in_executor(executor, cb) return wrap(f, loop=loop, executor=executor) </code> Anders Hovmöller has proposed a Python syntax extension to improve this code. It provides, for example return wrap(f, *, loop, executor) as a shorthand for return wrap(f, loop=loop, executor=executor) See: https://mail.python.org/pipermail/python-ideas/2018-September/053207.html I'd like us, in this thread, to discuss OTHER possible ways of improving this code. This could include refactoring, and the introduction of tools. I'm particularly interested in gathering alternatives, and at this time not much interesting in "knowing which one is best". -- Jonathan _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
