A compile time analog, for what it's worth, would work like this:

     int a = 4;
     BOOST_AUTO( tmp, repeat<3>(a) ); // internally calls ref_csv(a,a,a)
     BOOST_ASSERT( tmp[0] == 4 );
     BOOST_ASSERT( tmp[1] == 4 );
     BOOST_ASSERT( tmp[2] == 4 );
     BOOST_ASSERT( tmp.size() == 3 );
     tmp[0] = 1;
     BOOST_ASSERT( a == 1 );
     tmp[1] = 2;
     BOOST_ASSERT( a == 2 );
     tmp[2] = 3;
     BOOST_ASSERT( a == 3 );

It would be fairly to implement. I started here:
