| no alteration of code. It does mean that types that derive from iterator_range |
| may need to prefix <code class="computeroutput"><span class="keyword">this</span><span class="special">-></span></code> to the various member functions. |
| Additionally it has been noted that some calling code was relying on |
| member functions such as <code class="computeroutput"><span class="identifier">size</span><span class="special">()</span></code> being present despite the underlying |
| iterators not being random-access due to <code class="computeroutput"><span class="identifier">iterator_reference</span><span class="special"><</span><span class="identifier">Iter</span><span class="special">>::</span><span class="identifier">type</span></code> |
