But we already have asyncio and code based on asyncio coroutines.
To make it work I should always use costart() in places where asyncio
requires coroutine.

Maybe your proposal is better than current asyncio practice.
But now asyncio is built on top of two-step process, as you have
mentioned: building coroutine and waiting for it's result.

That's why I prefer `await` as replace for well-known `yield from`.
