I have no idea what he means by that, but I'm sure parrot does it.
Parrot supports full contintuations, and coroutines can be implemented
using continuations. I can't fathom anything you'd want to do with
coroutines that parrot's continuations wouldn't allow you to do.

That one's easy. Is that what he means by "true" coroutine? What's a
fake coroutine?
