Arent't "in" and contains already properties of a SortedRange object? How comes that your SortedRange is not sorted?

According to
https://dlang.org/phobos/std_algorithm_sorting.html#.isSorted
the check for sortedness would require O(r.length) evaluations. I don't think,
you really want to have this check run every evaluation of "in" or contains, do
you?

I have not noticed that contains() is a member of SortedRange.

So, you are right, I am closing the bug.
