Long ago UNIX had compiler writing tools like yacc and lex. I wonder if they are useful for exercises like this.

That's what I want to try next time. There are pros and cons in using the parser generator, but the tool seems to be useful at least if you want to create a small compiler which don't aim Clang-level diagnostics.
