Stuart,

Hah!  The guy that came up with it is a professor in the Computer
Science Dept. at UW-Parkside in Kenosha, WI...right in my neck of the
woods.  After showing this method and explaining how it's derived in
detail, he wrote, "Imagine presenting this to undergrads who have just a
lecture or two of SQL under their belts.  You DO get the chance to talk
about scoping of aliases..."
