From the keyboard of rbj@uunet.UU.NET (Root Boy Jim):
:Also, I am reluctant to
:use eval often, even in LISP. I find the scoping slightly more
:difficult to figure out.

It's no different than at any other time: it's dynamic, which 
means you can see something if your caller could.  This is
what often confuses people, most of whom are used to lexical 
scoping.  Of course, once you bring pass-by-reference and
pass-by-name into the picture, you quickly find yourself caught
it a maze of twisty, turn pathways, all alike.
