Sorry, that completely unspecified and vague scenario is irrelevant
in both theory and practice.  Why would you need to rename them?
They're internal functions: noone else but you needs to know or care
about them.  This technique doesn't suffer from any other problem
a function interface wouldn't have as well.  Can't tell why you're
trying to poke holes in such a well known and widely used Lisp
technique, but I must be off.
