This issue has some overlap to LWG <iref ref="4323"/>, and it would

affect the outcome wording of that issue for `unique`.

[<i>Drafting note:</i> If issue LWG <iref ref="4323"/> is decided to be acted upon and

the proposed solution accepted, the proposed complexity wording becomes:

</p>

<blockquote><p>

-11- <i>Complexity</i>: If `empty()` is `false`, exactly `size() - 1` applications

of the corresponding predicate, otherwise no applications of the predicate.

<ins>For each element erased as a result of this function call, at worst <tt>&#x1d4aa;(log n)</tt>

in the capacity of each block containing the element. Additionally, if any active blocks become

empty of elements as a result of the function call, at worst linear in the number of element

blocks.</ins>
