I mentioned Squirrel here:

And the applicability of my concerns to online games:

What is Squirrel's design focus in the foreign language interoperability realm?

Alberto, I would appreciate any insight you might have time to share, given the level of experience you have in optimizing for real-time execution performance, integrating across "360 degrees" of programming disciplines, and being the author of a VM and dynamic language.

Another relevant thread of discussion has started:

IMHO, the key point that comes from this that we should proliferate interfaces instead of (non-)interoperable data types, and that granularity of inheritance is most interoperable, thus virtual/prototype inheritance is a non-scalable paradigm.

Apologies in advance if readers here feel this thread is off-topic.  I felt Squirrel is a relevant VM to compare in this analysis.
