You learn things with Forth that you don't learn with Lisp. Foremost among these is the relationship between the highlevel language and the underlying computer.

You learn things with Forth that you don't learn with Lisp. Foremost among these is the relationship between the highlevel language and the underlying computer. In many Common Lisps you can write functions in assembler if you need to, but in a Forth compiler the assembler is right there. In fact if you have a native assembler it's very easy to bootstrap a baby Forth on top of it and then use that baby Forth to build a complete Forth. No C required. The feeling you get from doing this is one of complete mastery of the computation process. It's awesome.
