@andybalaam, thank you for your contribution to CPython. @1st1 and @asvetlov had marked this on the bug tracker as "won't fix", so I'm going to close this with that in mind. If the status changes, then this can be reopened. |

See http://bugs.python.org/issue30782 - I propose adding a "limit" argument to asyncio.as_completed.
Justification is in the linked bug and my blog posts: http://www.artificialworlds.net/blog/2017/06/12/making-100-million-requests-with-python-aiohttp/
The "Allow passing a coroutine to as_completed" part may be the most controversial because it turns off checking for some types of error, but I think it is necessary to achieve what I am trying to do.
