   I love the idea of putting lookup within the language.
   Perhaps the VM shouldnt implement any kind of inheritance at all?

Can you say Scheme? This is not an entirely facetious suggestion. It
sounds like this discussion is leading to a small, regular easily
optimized language that can be used to build higher-level language
features like inheritance and polymorphic procedures.

Excuse me for leading this perhaps too far astray. I don't want to
start discussing Scheme (or compiling for continuations, etc.) but it
is a reference point when discussing core languages vs. extensions
that can be built with a core.
