> In Evgeny's example the 'task' is 'coro1' (not 'coro2'). It has plenty of yield points after being cancelled. Since coro1 waiting coro2 when cancelling, Task(coro1).cancel() redirect to Task(coro2).cancel(). But I was wrong about "CancelledError is thrown to coro2." Task(coro2) is cancelled in last step. CancelledError is not thrown to coro2 actually. So there is chance to detect it.
