Is it possible to cast a 2d static length array to a 1d static length array?

E.g.
int[2][2] a = [[1,2],[3,4]];
int[4]    b = cast(int[4])a;

Is not the byte data in memory exactly the same?

*( [pos,size].ptr .cst!(void*) .cst!(int[4]*) )
(using dub `cst` library) or
*( cast(int[4]*)(cast(void*)([pos,size].ptr)) )

Okay, this works but is this the best way?!

This should work
int[4] b = *(cast(int[4]*)a.ptr);
