You may be already aware with this, but if not, Walker actually did write a small Forth (ATLAST -- https://www.fourmilab.ch/atlast/) which was used for (I think) DXFTOOL (a file converter).

It was later used by a small computer graphics studio in Tennessee for a blue/green screen matting utility and a fast roto-paint program.

Very interesting, even if tools like ATLAST had been available for free back then, AutoLISP would have won. HP-41CV programming had already wired my brain for stack thinking, and LISP felt like the natural next step. Forth was too raw, LISP had just enough structure.
