Range represents a range as follows. Member @start is the inclusive lower bound, member @end is the exclusive upper bound. Zero @end is special: if @start is also zero, the range is empty, else @end is to be interpreted as 2^64. No other empty ranges may occur. The range [0,2^64-1] cannot be represented. If you try to create it with range_set_bounds1(), you get the empty range instead. If you try to create it with range_set_bounds() or range_extend(), assertions fail. Before range_set_bounds() existed, the open-coded creation usually got you the empty range instead. Open deathtrap. Moreover, the code dealing with the janus-faced @end is too clever by half. Dumb this down to a more pedestrian representation: members @lob and @upb are inclusive lower and upper bounds. The empty range is encoded as @lob = 1, @upb = 0.
