    (1) ...  Eventually, it will send a message to an ENTITY or INSTANCE
        if CAR or CDR of it is taken.

Why are you bothering with this?  I don't see how CAR or CDR can be thought
of as generic operations.  I view them as primitives for manipulating
conses, and nothing more.  Alternate primitives should be created for
indirection through locatives, etc.

The only way such a feature would be useful would be in using code written in
terms of CAR and CDR to manipulate objects which are structurally similar to
lists.  I think this is something to be discouraged.
