Subject: Range#size

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?
