      This is simply untrue.  Float ranges and Time ranges are both very
useful, especially if you extend them (which in a language like ruby you
can).  The sort of operations you'll want on Intervals (Time ranges) are
slightly different than you'll want on Error_bars, Bounding_box_sides,
and other sorts of Float ranges anyway.
      If anything, I'd expand the range of ranges.
