I completely agree with this. What I don't understand is why example #2 can't work the same. > "await bar()" and "await wait_for(bar())" are actually quite > different. Let me illustrate with an example: > > b1 = bar() > # bar() is not running yet > await b1 > > b2 = wait_for(bar()) > # bar() was wrapped into a Task and is being running right now > await b2 > > Usually this difference is subtle, but in asyncio it's perfectly fine > to never await on b2, just let it run until it completes. If you > don't "await b1" -- b1 simply will never run. Perhaps... But still, why doesn't bar() inherit the LC *at the point where it was instantiated* (i.e. foo()'s LC in the examples)? The fact that it's *later* passed to wait_for() shouldn't matter, right? Or should it?
