Well, it's not about what's needed or not, there are obviously
several ways to do this as we have seen in this thread
already, and what `cl-defun' offers is another such solution,
one that some people would say is more clean than the
solutions with `or' and `setq'/`let' ...

Again, there is no need to do any of this but it remains that
`cl-defun' is an Elisp macro ...
