Well, I don't know how "true" coroutines are defined, but Parrot, as
it's CPS based, has no problems with coroutines and there are no
restrictions to coroutines, AFAIK.
To be honest, I hadn't thought of this, either (this "true"-ness of
coroutines), but then again, I'm no expert on these thing

Okay, this has been an ongoing source of annoyance, and I think it's

We need to get search paths for loading of stuff into parrot, both at

Mark,
This can be an issue, however I think it is easily solved.
1) Use a mean between the most efficient and least efficient

In many situations, your more efficient programmer is managing your

You can switch off buffering on stdout by doing:
