Re: optimizing defconst

[Richard Stallman]

    What about an option to make a constant read-only, something like

    (defconst ...
       :read-only t)

It is work which is not necessary.
It is better if we save our time for other things.

    Then the byte-compiler could check to see if a constant (or any
    variable for that matter) is really read-only and optimize it away.

It is a clean way to do this job, but this job does not need to be
done at all.
