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.)
