Looking at the calc source code was not terribly helpful, since it is
barely documented. The info page can help somewhat, though.
Doing a little bit of digging, it looks like you can bind variables for
=calc-eval= like so:
#+BEGIN_SRC elisp
(let ((var-a "[1, 2, 3]"))
(calc-eval "evalv(reduce(add, a))"))
#+END_SRC
#+RESULTS:
: 6
This pattern could be used for variable binding. It would mean wrapping
the code to be evaluated in =evalv=. If I get some time, I might
investigate writing a patch to do this.
