<para>Note that this class is suggested to be part of the next
Technical Report, which will extend the C++ Standard (see
<ulink url="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2003/n1548.htm">http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2003/n1548.htm</ulink>).</para>
<para>Update: <code>std::array</code> is (as of C++11) part of the C++ standard.
The differences between <code>boost::array</code> and <code>std::array</code> are minimal.
If you are using C++11, you should consider using <code>std::array</code> instead of <code>boost::array</code>.

<para>Class <code><classname>array</classname></code> fulfills most
but not all of the requirements of "reversible containers" (see

*
* 14 Apr 2012 - (mtc) Added support for boost::hash
* 28 Dec 2010 - (mtc) Added cbegin and cend (and crbegin and crend) for C++Ox compatibility.
* 10 Mar 2010 - (mtc) fill method added, matching resolution of the standard library working group.
* See <http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#776> or Trac issue #3168
* Eventually, we should remove "assign" which is now a synonym for "fill" (Marshall Clow)
