No one in this thread, unless I missed
something, has made an attempt at defining,
explaining, and showing with examples how
inlining is done and what it means in Elisp:

(defun add-two-digits (a b)
  (+ a b) )
(defsubst add-two-digits-inline (i j)
  (+ i j) )

(defun add-it ()
  (add-two-digits 5 10)
  (add-two-digits-inline 15 5) )

This byte-compiles with no warnings/errors.

So what happens then, and what happens when
"add-it" is called?
