>So the functionality is correct, but not in a way the author would like it to, therefore it's a lie to claim it works. Eh? It's fine to criticize that the implementation isn't any good, of course, but employing such narrow definition of "works" and then calling someone a "liar" over it seems rather, eh, much.

As far as I understood the article the coroutines don't work?

If I write asynchronous code via a coroutine and one coroutine with io prevents all other coroutines from running that is not a working coroutine.
