Encouraged by Michael Heerdegen, I might want to start with a simple metacircular evaluator (just as an exercise, further to be transformed e.g. to a blog post for other learners of (Emacs) Lisp), and then I=E2=80=99d like to write a more useful thing analyzing Elisp code. So, I have an s-exp in the buffer, and I want to read it into a variable, where it will become an Elisp list. How do I do that? Notice that I=E2=80=99d like to preserve all the funny things like (back)= quotes or commas, since I want to deal with them in my code. That=E2=80=99s why I assume that the =E2=80=98read=E2=80=99 function is not exactly what I=E2= =80=99m looking for.
