> to allow concurrency, you should use asyncio.create_task on coro (formerly ensure_future).

This is misleading... you can use asyncio.gather which does this internally [0].

Only if you wish to collect tasks where you schedule them, accumulate the results and don't need to limit concurrency.

Serious question, why would you limit concurrency in async world? You’re still on a single thread, why would you want to only schedule n things at a time?
