Re: redisplay system of emacs

[Richard Stallman]

    Whenever I look at the Emacs C codebase, I think that a language like
    the described above would do wonders replacing a good chunk of it.

The code written in C in Emacs is mostly in C so it can be as fast as
possible.  To move it into such a language would be a big practical
loss.

There is some code that was originally in C but doesn't need to be
fast.  We have rewritten some of that code in Lisp in recent years.
If more such C code remains, we could move that to Lisp too.
