Indeed, this is a class of genuine bugs.

Not just that -- a user cannot accidentally refer to $vars like she
can to probes (there is no equivalent of "probe * {}" like "$*"), so
this class is much less interesting.

It will become instantly annoying.  If you like, check in two copies
of the tests, once with -u (and you might as well instantly mark it
kfail), and once without (which should pass).
