[section:insertion_hints Insertion hints in associative containers and preserving
insertion ordering for elements with equivalent keys]
[@http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#233 LWG Issue #233] corrected a defect
in C++98 and specified how equivalent keys were to be inserted in associative containers. [*Boost.Container]
implements the C++11 changes that were specified in [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1780.html N1780
['Comments on LWG issue 233: Insertion hints in associative containers]]:
* `a_eq.insert(t)`: If a range containing elements equivalent to t exists in a_eq, t is inserted at the end of that range.
* `a_eq.insert(p,t)`: t is inserted as close as possible to the position just prior to p.
