Good. This is more orthogonal. Meta-information belongs in meta-tables.

Great. Again, it's more orthogonal and smaller.

So, this is in essence a user-defined type like the "filehandle" type?
It's not another built-in type, I hope?

Could the coroutine be set up to work in an OO way like
the file handles? So we could say x:resume(1,2,3).    
Thank you for your hard work.
