I'd like to try the Coro together with EV.

There are a few code snippets:

async {
    while (1) {
    ...
    cede;
    }
};

When I use only Coro, everything's fine.

But when I try to connect EV, weird things happen, which can be explained only by the fact cede doesn't pass the control to EV.

It forces me to use cede and Coro::Timer::sleep together:

async {
    while (1) {
    ...
    sleep 0; cede;
    }
};

Coro::Timer::sleep - it's an explicit call to EV.

Has anyone faced such an issue?

UPDATE:
I was wrong, Coro::AnyEvent::poll really helps.
This is the same as sleep(0).
I was pulling his leg, Coro’s author, shame on me.
I just could not figure it out that Coro can be used without IO in practice And those using IO have Coro::AnyEvent::poll.
Still, I learnt that Marc Lehmann is a patient and very polite person.
I got a good lesson too: don’t make the output on STDIN artificially.
