So many words to say: Scheme.

:)

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 really wanted to Lisp as a main programming language, and sometimes I still do.

I just find readability such a hurdle regardless of how long I used it. I didn't find that it ever became as natural as the other group of programming languages.

I find a procedural style of programming so much easier to reason about, both when writing and reading.

Either way, I'm really happy I took some time to learn it and use it a little at some point.
