OK, that makes sense, but the spec doesn't say that.  Page 3-43 says that
it is "called to determine the effective method", but does not ever
specify what the returned value is.  I apparently made an invalid
assumption about what was intended.  I see now that page 1-28 says that it
"returns a Lisp form that defines the effective method", but it doesn't
say anything about what it can be expected to look like.
