	(did some of unix-survival/emacs-scheme here in spring 1993)

	lecture 6
* recursive-moment
	used as another lecture to talk about recursion in spring 1993, fall 93
		this is about the problems remove-2nd
			and last-adj-out (remove-last)
	Instead it might be better to do section 4.2 in the book here...
		and not assign remove-2nd or something like that until after
		a lecture like this.
