Unless you think of the "length" as being "the difference between one side
and the other". The pencil on my desk may delimit an infinite range of
positions, but the length of that range is still just shy of 4".

Or you could think of Range.length as being similar to Array.length and
being "the number of elements in the expansion of the range". 

  irb(main):001:0> length = 0
  => 0
  irb(main):002:0> (1.0 .. 3.0).each{ length = length + 1 }
  => 1.0..3.0
  irb(main):003:0> length
  => 3
