It looks like it's indeed okay to access boost::array::elems directly. 
But tr1::array::elems is marked as "Exposition only". Other TR1 
implementations have indeed named their tr1::array data member differently.

Unfortunately c_array() is also specific to Boost.  So I've proposed to 
add this member function to std::array as well (LWG issue #930), 
returning a reference to the array.  (Including overloads for const and 
rvalue arrays.)

   Kind regards, Niels
