Lisp as a Y combinator

.

This concept ties into:

• Metacircular Evaluators: In SICP, they introduce the concept of a metacircular evaluator, which is an interpreter for Lisp written in Lisp itself. This is a direct example of “Lisp = Process(Lisp)”, where the “Process” is the act of interpretation or implementation.

Sussman’s statement is both a philosophical and practical insight into the nature of Lisp, highlighting its self-referential capabilities and the elegance of its design in terms of theoretical computer science concepts like fixed points.
