I was working on a good solution for this which would allow you to create a test range with pretty much any combination of range capabilities you wanted (as well as providing a default set of ranges to test with), but some compiler bugs were blocking me at the time, and I haven't gotten back to it yet. I really should finish that up. - Jonathan M Davis
