I think I did not express myself clearly (or maybe I misunderstood your
original comment). My apologies.

I was making a "philosophical" point that, wrt software tools, there is
no fundamental difference between "users" and "developers" (as
opposed to, say, the difference between users and developers of a word
processor or a web browser).

This is similar to the "blueprint/spec" and "product" distinction: a
blueprint for a bridge is _not_ a bridge, no matter how clear and
detailed it is.  A very detailed spec for a computer program is, in a
way, _the_ computer program it describes (cf. pseudocode).

Of course I understand CLISP internal better than you do at this time.
However, the readline completion feature is useful to you just as much
as it is useful to me. We are in the same boat, so to speak.

You can start your quest by replacing sys::completion with, say,

(defun sys::completion (string start end)
  (list "foo" "foo1" "foo2"))

Now, whenever you hit TAB, you get "foo" inserted and "foo1" and "foo2"
suggested (or something like that).

The current behavior is described here:
