If you want to look into low-effort things to contribute, you may
consider helping to clean up https://tracker.orgmode.org/bugs. A number
of bugs there are already resolved or got no reply and should be closed
- see https://tracker.orgmode.org/howto

Applied against the main branch, thanks!


Unfortunately, fixing this warning breaks org-table logic and 
tests.

Oh my goodness.  That is... sigh.  Wow.

This is now beyond the "trivial fix" level of effort that I was 
prepared to invest to make this warning go away.  Like Rudolf 
Adamkovič and others before him, I now retire to my country 
estate, to simultaneously lick my wounds and rest on my laurels 
(which I guess is better than licking my laurels and resting on my 
wounds).


Thank you for noticing, and for adding the FIXME later.

Best regards,
-Karl

I added a FIXME explaining the issue to make the problem more clear. I
think this is the third attempted fix of this warning on the list :)

Canceled.

Ouch. Reverted.

I took back control over my zombie clone and put him back to sleep in
his coffin.

Subject: [PATCH] lisp/org-table.el: fix warning about `eq' usage

* lisp/org-table.el (org-table-make-reference): Use `equal' instead of
`eq' to compare strings.

This change makes the following warning go away:

  Warning (comp): org-table.el:2867:23: \
  Warning: `eq' called with literal string that may never match (arg 2)

This change does not affect the behavior of `org-table-make-reference'
because `eq' treats all instances of the empty string as the same
object anyway, e.g., `(eq (string-trim "aaabbb" "a+" "b+") "")' ==> t.
The only effect of this change is to eliminate the warning.
