https://svn.boost.org/trac10/ticket/6944 <p> Due to an omitted namespace specification, the <a class="missing wiki">BidirectionalRangeConcept</a> and <a class="missing wiki">RandomAccessRangeConcept</a> inside &lt;boost\range\concepts.hpp&gt; use the STL iterator concept checking classes in &lt;boost\concept_check.hpp&gt; instead of the appropriate concepts inside the same file. </p> <p> This issue was actually noticed in ticket <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/4355" title="#4355: Patches: without namespace 'range_detail' (closed: fixed)">#4355</a>, but a different fix was applied. </p> <p> The reason that the Range concepts should not use the STL iterator concepts is because the Range concepts only require the relevant traversal concept.
