The docs <https://orgmode.org/worg/org-contrib/babel/intro.html> have this
example:
#+name: square
#+header: :var x=0
#+begin_src python
return x*x
#+end_src
#+call: square(x=6)
...so yes, "return", but with
(defun myelsquare (x)
(* x x))
isn't the final thing evaluated what is "returned" with Elisp? AFAIK there
is no explicit return with Elisp. #+call can't really call a function, only
named blocks of REPL-style calculator snippets?
Also, today I find that a new start of Emacs doesn't load my LOB file, i.e.,
(custom-set-variables
...
'(org-babel-lob-files (quote ("~/org/worg/library-of-babel.org")))
...
was being blown off, i.e., not populating the org-babel-library-of-babel
variable. But today org-babel-lob-injest does seem to work, i.e., it did
populate org-babel-library-of-babel. I wonder what's up.
