No, you don't.  You can define macros at Boot level.  They get

It looks to me that you don't understand the full power of Boot.

I'm amazed you have to ask, but since you asked, yes.  I've looked at it.

But it does NOT NEED to.  What you believe to be intimate dependency is just 
implementation details you've focused on too much to the point of losing 
sight of thr forest.

yes, but the Axiom run time system does not need full Lisp.  
In fact, the algebra can be compiled to something more efficient that
the use of Lisp as done.
