Comment (by marshall):

 Yes, it would - but would people actually use it?

 Do people use:
 {{{
 std::array<int, 2> arr;
 std::get<2>(arr) = -1;
 }}}
 in C++11 - or do they just write `arr[2] = -1;` ?

 `boost::array` (and `std::array`, and `std::vector`) all have runtime
 checking through the member function `at`.
 {{{
 boost::array<int, 2> arr;
 arr.at(2) = -1;    // will throw an exception
 }}}
