I like this tutorial, but it's worth noting that you're building your own lisp with the author's bespoke parser generator.

Yes. I followed this tutorial a few years ago and found this to be quite disappointing.

It seems the author has added an appendix [0] where he replaces the library parser with a hand-rolled one.

The book skips major components of a lisp implementation - garbage collection, macros - as "bonus projects" to be implemented by nhe reader.
