    I am in agreement with everything Moon has said, except for the
    following paragraph:

	Right now, Common Lisp has two kinds of cells: global cells and local
	cells.  Local cells have lexical extent, while global cells have global
	extent and can be referenced from anywhere except where they are shadowed
	by a local cell referenced by the same name.

    I believe this paragraph confuses the notions of extent and scope.

Quite right.  I must have meant to say "scope", but spazzed.
