I wasn't asking whether it was straightforward, just possible.
This should work:
template<class T> class vectorN
T x1, x2, ..., xN;
T& operator(unsigned int i)
struct checker:public vectorN
Since elements of arrays are required to be in contiguous memory locations,
the variables x1 through xN must also be contigous if the static assert
passes. I don't know if this is a necessary condition, but it's certainly
Here I'm assuming that the compiler aligns to at most 256 bytes.
