Don't forget that Common Lisp and Scheme have a very different user-base
and goals.  These are languages whose target users are real programmers,
and where its considered normal to let a program core-dump if the
programmer has given incorrect compiler hints in the form of
type annotations.

Most users of Elisp on the other hand would not describe themselves as
programmers.

If they prefer performance, they won't be coding in Elisp, I'm afraid.
