Another Lisp of note is AutoLISP.

Elisp::Emacs as AutoLISP::AutoCAD. AutoLISP was my first introduction to Lisp-style language. When I first started using it (1987) for macros in AutoCAD, I really had no idea what Lisp was. It was just a fun and easy way to automate AutoCAD.

I had forgotten about this. The last I saw this was 20+ years ago!

Adding and substracting 3D-objects was the same as in OpensCAD.

Strange they did not make OpenSCAD in AutoLISP-style.

I have to read the manual all the time, because I never learn the weird syntax of OpenSCAD for-statement.
