Kind of like LISP. When I read McCarthy's original papers, it had that same feeling of simplicity, and you could easily see how it mapped directly to the hardware. Original papers are often the best. Chuck Moores book on FORTH was finally released as a PDF, but he wrote it in the early 1970's. Amazing. I knew FORTH was linked to LISP, and the link is explained in there.
