(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.
