Why doesn't a Range does extend Pair? It's pretty clear (to me at least) that a range is a pair of values.
Because the Pair is in our tuple package, it means that it should follow tuple logic and be thought of as an ordered list of elements, in this case two elements. The methods that Range has that are not in Pair could be moved there. -- Thank you, Gary http://garygregory.wordpress.com/ http://garygregory.com/ http://people.apache.org/~ggregory/ http://twitter.com/GaryGregory
