Build a Scheme interpreter in Python covering tokenization, eval/apply loop, environment frames with lexical and dynamic scoping, special forms (define/lambda/if/let/cond), Pair-based linked lists, built-in procedures, and a REPL. Use when implementing a Scheme dialect in Python, teaching programming language concepts via SICP-style interpreters, or understanding how Lisp evaluates code as data.
