Right. That is odd.

It is the binary search that sorts them. Like this:

1. The list starts out empty, which is sorted.

2. When each link is added, the place it should be is found via the
   binary search, and it is inserted there (if it is not a duplicate),
   so the list stays sorted.

It seems very suboptimal until you consider we already have to do the
binary search for the duplicate check.

Is there any pattern to the way are the member attributes are unsorted?
