lovely from-scratch implementation, without the magic and complexity of lex and yacc. brings back memories from 30+ years ago when I implemented a subset of C in C using lex and yacc in a compiler course.

in your blog, i would have liked to see the BNF grammar (without having to peek into the code).

now, heres your next assignment :) - do the same for functional programming (lambda calc) or logic programming (prolog). That would round out the education on languages and compilers for computation.
