electric-*-mode and font-lock-mode are part of GNU Emacs and XEmacs
now, not surprisingly.

GNU Emacs and XEmacs are almost capable of doing this now -- in Lisp
interaction mode or inferior Lisp mode, you can move your cursor to the
end of a defun and hit control-J, which passes the current sexp to the
appropriate Lisp interpreter. In some environments, this means that
the function will be redefined.
A lot of folks from LMI, Symbolics, and Lucid have contributed a lot of
code to GNU Emacs and XEmacs.
