I would have written it as follows:
(defun dev-charseq (lower &optional upper)
(if (null upper) (setq upper lower))
(loop for x from lower to upper
collect (indian-glyph-char x 'devanagiri)))
I changed "from" to "lower" and "to" to "upper" since the loop
looks sort of funny otherwise.

I did a grep through the sources and there are 118 files that
already contain the line,
(eval-when-compile (require 'cl))
So I hope adding another of these won't be a problem.
