That's fantastic.

This depends if you'd rather execute newlisp code blocks in a "session"
(i.e. in an inferior newlisp buffer, which would require newlisp-mode),
or if you'd rather evaluate newlisp externally.  Most languages support
both types of evaluation, but I'd recommend starting with a single
execution mode (whichever will be simpler to implement), and then
incrementally adding functionality.

I just installed newlisp locally, it looks like a nice language, I may
start using this as I've been looking for a light-weight lisp/scheme for
small scripting tasks.

I just put together the following, which works for me as a simple
evaluation function -- note this takes the "external evaluation" path.

--8<---------------cut here---------------start------------->8---
(defun org-babel-execute:newlisp (body params)
  (let ((tmp-file (make-temp-file "org-babel-newlisp")))
    (with-temp-file tmp-file
      (insert
       (format "(println (begin\n%s\n))\n(exit)" body)))
    (prog1 (org-babel-eval (format "newlisp -f %s" tmp-file) "")
      (delete-file tmp-file))))
--8<---------------cut here---------------end--------------->8---

Note, this doesn't make use of *any* of Babels header argument
functionality, but it could serve as a place to start.

Please don't be shy about asking questions, we can be a very
understanding bunch.

Happy Hacking -- Eric
