Maybe, not always. Both would be nice. The offset isn't the element with
the index N. It's the next set element whose index is >= that of the
selected offset. There's no simple way of knowing how many set elements
come before or after offset - possibly zero. In order to insert something
after the first element you have to find the index of the first element.

Yes please. Everybody wants more data structures. (I know... patches
accepted.)
