In Common Lisp (and presumably Emacs Lisp), functions are as first-class
as in Scheme and elsewhere. You just have to do a bit extra to use them
as first-class values, that's all. There aren't any fundamental
restrictions there because of that.
(In Common Lisp, you also get lexical scoping by default, so you get
what you expect if you come from a functional programming background.)
