Comment(by niels_dekker):

 Update: Yesterday, the Standard Library Working Group has discussed my
 proposal to add ''c_array()'' member functions to ''std::array'', in Santa
 Cruz. Unfortunately: ''There was not enough consensus that this was
 sufficiently useful.''
 http://home.roadrunner.com/~hinnant/issue_review/lwg-closed.html#930  So
 now it is unlikely that ''std::array'' will offer an easy way to get a
 reference to its internal built-in array.

 I wonder if it's safe to cast ''std::array<T,N>'' to a pointer-to-array,
 as follows:
 {{{
 static_cast<T(*)[N]>(static_cast<void*>(arr.data()));
 }}}
