237. Undefined expression in complexity specification

Discussion:

The complexity specification in paragraph 6 says that the complexity is linear in first - last. Even if operator-() is defined on iterators this term is in general undefined because it would have to be last - first.

Proposed resolution:

Change paragraph 6 from

Linear in first - last.

to become

Linear in distance(first, last).
