dear list,

does anyone object to adding the method :size to class Range?

class Range
  def size
    max-min+1
  end
end

i think it's useful. maybe others too. i'd like to see it
added to the core. here is the test for Range#size in case
it's really added.

def test_range_size
  assert_equal 1, (1..1).size
  assert_equal 2, (1..2).size
  assert_equal 3, (1..3).size
  assert_equal 0, (1..1).size
  assert_equal 1, (1...2).size
end

what do you think?
