The programmer would have to update it.  I could see this working for
trivial cases, but too many problems would arise beyond them.  Instead of
POINT, one might use KEY.  However, it seems to defeat the unstated point
of one "step" (no sort).

...or even the situation when the positional correspondence is a mismatch,
i.e. observation 2 in dataset 2 is a new value but still matches
observation 1 n dataset 1.  It could be done, but would require some
coding....
