But what if you don't need `await`? A coroutine call `mycoro()` could act as the actual `await mycoro()`. If you really want `mycoro()` actual behavior, you could write `async mycoro()`.
The way async/await is implemented, it's not feasible to wait until runtime to decide whether a given call should be treated as an await or not. Different bytecode is generated for it, and the behaviour of the enclosing function is quite different right from the start, before the await is even reached. Other implementation strategies are possible that would enable "async" and "await" to be eliminated. But there are many people, including Guido, who regard the need for these as a feature rather than a bug, because they mark the places where suspensions can occur. So you would have to convince those people that these keywords *should* be eliminated, before thinking about how to achieve it. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
