Indeed. And, given the "XX in less than YY lines of code" framing of the title, I was actually hoping for something a little more along the lines of clever code. This this is a pretty pedestrian interpreter, honestly. It's not bad code, just ... exactly what I would expect an interpreter for a tiny language to look like.
Agreed. It's a nice college freshman first project.
Hmm, a compiler it may not be, but I doubt many college freshmen could do this as a first project.
The final project for everyone in my intro course was to write a LISP interpreter. Have we fallen so far?
Terrific example for people that want to understand how interpreters work.
Not perfect. But perfect for getting your feet wet.
