How could I intervene in the evaluation process so as whenever a

You can't intervene in the evaulation process of CL:EVAL. There are no
hooks for doing so, as Pascal Bourguignon points out.

The hooks are symbol macros and macros. But granted, there's no hook to
change the self evaluation of non symbol atoms.


You would have to implement your own evaluator and use that if you want
to have different evaluation semantics. So that would be one option.
