It's fine with me.  I've been unhappy with this approach for a
long time, and it'd be great to get rid of that ugly union.  The
only reason I didn't change it was that I didn't have an idea I
was really happy with.  What's the plan?

By the way, when it comes to FREQUENCIES I think that this is
useful enough that we should try to make it into a library, as we
do for, say, moments and Levene calculations.
