I found plist-put changes the literal argument I pass to a function:
(defun test ()
(test-2 '(:a b)))
(defun test-2 (form)
(print form)
(plist-put form :a 'c)
nil)
(progn (test) (test))
(:a b)
(:a c)
nil
I thought Elisp is pass-by-copy? Is this expected?
P.S., (setf (alist-get )) does the same, I guess this IS expected?
