I think that the option of "active and direct" collaboration between Cocoon and Rhino would be better for both. It might increase their community, create a solid political link (that today is missing), give us a meritocratic control on the platform (cocoon is probably going to become one of the most important rhino customers).
So, it might be good to start talking to them *before* we even attempt to do anything from a code perspective, maybe they have ideas on how to solve things easily or maybe even converge to a common point.
Hmmm... don't forget that this is Open Source (oh well, I bet you know that ;-)) and as NKB loves to say, discussions get forgotten, just code remains. :-)
I would say then that it would be nice to go to the Rhino community with suggestions *and* some code. I have been looking at it more thouroughly and as of now I think that the real problem is not really Rhino missing continuations, but Rhino being coded not to be extensible: most classes we need to extend are final, and members we need access to are private. So far Cristopher and I went quite the "easy" way, changing accesses and declarations just when needed, but it won't take a huge effort to refactor the few classes we need in order (adding getter/setters and the like) to make them really extensible.
Once this is done, the continuation-specific code might happily live in the Cocoon CVS as a Rhino extension if the Mozilla community is not willing to accept it (and actually I don't really see a real reason for them to include it ATM since Cocoon would be the only customer for that) and we might control it with Gump guarding against back-incompatible changes.
This will take no more than a few hours of (boring) coding, and I'm willing undertake the effort if it sounds reasonable to us all, and produce a first working extensible JavaScript interpreter that might be committed in Rhino. Meanwhile, we can start approaching the Rhino guys and see what they think aboout it.
How does it sound?
