It looks like this implementation reaches about the same level of parser
support as the stuff that I had coded up a few months ago at the airport
within a couple of hours [0][1], and I had sent the student the code, so

But as others had commented already, the meat of the problem is how
MERGE statement *execution* is supposed to work.
