> Since (x) is uninitialized, so is (x.i).
But what if x.i gets initialized, is x still uninitialized?
struct X { int i; };
struct Y { int i; int j; };
int main()
{
X x;
x.i = 0; // is 'x' initialized now?
Y y;
y.i = 0; // is 'y' initialized now?
y.j = 0; // is 'y' initialized now?
}
It would be possible to track the initialization of each subobject *and* the
aggregate, but it would be more overhead
