Well ... I guess my point of view is that Forth is the ultimate "virtual
machine", and that the good folks who created GForth exploited a feature
in GCC that's outside the ANSI C standard to create a "fast, portable,
virtual machine." In passing, I found it interesting that at least one
of the Ruby VMs posted on the link a couple of messages back uses the
same "virtual machine generation" concept that GForth uses.

So ... does Parrot use this? I'm pretty sure YARV doesn't. Meanwhile,
have a look at
