Thanks, Billy.  I was starting to wonder if
*anyone* was going come around to appreciating
its quirky wholesome-ness. <wink>

/ and // weren't my first choice (< and <= were -- I'm still working
on that approach) but since they had the advantage of actually
*working* in this scheme, I just went with it.  In my mind
/ seems "thinner" than // so it seems better matched to the
"thinner" interior interval whereas // seems better matched
to the *thicker* inclusive interval.  Also, / seems better
matched to < (>) and // seems better matched to <= (>=).
