Fare and others have been promoting the idea
of a reflective system.  I am familiar with this term
in several contexts and I'd like a little clarification.

Does reflective mean anything more than the usual
Lisp ability to get a hold of environments, code and

Does reflective extend to the 3Lisp concept of an
infinite reflective tower?
