Don't know if you had time to look at this yet, but another possible
hack would be to use the fact that struct { int x[N]; } is bit
compatible with int[N] and can be passed/assigned by value. E.g.
struct wrapped_array {
int x[3];
};
int main(int argc, char** argv) {
int src[3];
int dest[3];
*((struct wrapped_array *) &dest) = *((struct wrapped_array *) &src);
}
OTOH, it might make sense to simply add array members as a special
case in struct conversion.
