Right, exactly.  I don't claim that we have a perfect solution for
approximate matching; we don't.  But I think we should provide an
API function that is defined to do approximate matching, with the
understanding that the details of its behavior will change (for the
better hopefully) from release to release.  The first version might
not be very good, but we can improve it.
