Why can't Elisp be compiled as well?

With "dynamic", do you mean for example one can
change a defun, re-eval it, and the next call,
still from the same process, will execute the
new, modified version?

If so, that's a feature we all love and that's
why Elisp is so addicting because it gives
instant feedback. Still, we do it just to
a tiny tiny fraction of mostly our own Elisp.
The rest stays the same.
