Lecture 7A: Metacircular Evaluator, Part 1
MIT OpenCourseWare
Lecture 7A from MIT 6.001 (SICP) by Abelson and Sussman introduces the metacircular evaluator, a Scheme interpreter written in Scheme. It shows how evaluating a program is itself a program.
HN holds the SICP lectures up as joyful classics, and this lecture as the moment the evaluator is revealed.
