Thanks for your pull request, @dukc! We are looking forward to reviewing it, and you should be hearing from a maintainer soon.

Some tips to help speed things up:

• smaller, focused PRs are easier to review than big ones

• try not to mix up refactoring or style changes with bug fixes or feature enhancements

• provide helpful commit messages explaining the rationale behind each change

Bear in mind that large or tricky changes may require multiple rounds of review and revision.

Please see CONTRIBUTING.md for more information.

Extraneous whitespace

This is just stating implementation details. Also needs a Params: and Returns: section.

[dukc]

I object to that latter part, because other member functions lack them too.

I recall somebody saying that D's in operator is reserved for O(1)-algorithms. SortedRange.contains is O(log(n)).

@nordlow according to http://dlang.org/phobos/std_container (see at the end) in taking O(log(n)) is absolutely acceptable and expected.
