I want to call a specific coro (let's say the one in $ca, and when $ca calls cede, it should return to my original ($main) coro.

And I want that to happen several times, so throwing an exception instead of calling cede in $ca is not an option.

Update: we talked a lot on the CB, and it seems that Coro::Channel will help me a great deal. I'll have to experiment with it a bit before I can tell if it actually works.
