There isn't any other way to discover that the verb on the bottom of the stack
is really `huh' and not whatever the first word on the command-line was.

It wouldn't be trivial to use numbers here; that information isn't kept around
after the verb is called.  It would be easy to switch over to the full set of
verb names instead of whatever the caller used, but that would be an
incompatible change to the callers() function (and no, I don't want to make the
two kinds of stack lists different).
