Boost C++ Libraries: Ticket #9736: [documentation] document the size() extension points https://svn.boost.org/trac10/ticket/9736 <p> I added optimisations and extension-points to efficiently get the size() of a range. This means that when passing a type such as std::list that an optimal size() function is chosen in preference to performing std::distance on bidirectional iterators. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9736 Trac 1.4.3
