No. We are talking about an editor here, not a number crunching
package. One fundamental difference is that a vast majority of Emacs
Lisp constructs is _supposed_ to have side effects, in spite of being
written in a functional language.

Emacs is not a browser, it is an editor. If I execute some keystrokes
that will mark a region and then press the delete key before the
operation that will mark the region actually has completed, I won't be
happy if it instead deletes what happens to be at the time marked by
something else. I don't want Emacs to start executing keystrokes
before it has processed the previous keystrokes. I _want_ Emacs in
general to process the things in the correct order when editing.

See above comment from Stefan.
