+<p>
+`basic_stacktrace` is explicitly specified as a reversible container, an allocator-aware container, 
+and a const-qualified sequence container, with members `begin`/`end`, `rbegin`/`rend`,
+`cbegin`/`cend`, `crbegin`/`crend`, `empty`, `size`, etc.
+<p/>
+Thus, it's worth making the corresponding free functions available when introducing
+<code>&lt;stacktrace&gt;</code>, just like other containers.
