get top bit set? #86

Is there no way to get the top bit but to iterate from set.Len()-1 down and set.Test?

You can call the Test functions on all bits, irrespective of its index.

Please elaborate. Providing a code sample would be a good way to communicate your issue.

Looking closer now I think I was looking for a reverse NextSet. My use is not super performant so iterating Test backwards from Len-1 is working well. Thanks!

Your issue is valid and easily implemented. I have re-titled it.
