Detailed Description

A trivial output iterator that counts assignments.

This is useful when you need a null container. When a function writes to an output iterator, but you do not need that result, you can use this trivial output iterator.

Post-increment.

Usually one returns the object and not a reference to it. Here I need to return a reference for the counting to work.

Reimplemented from TrivialOutputIterator.
