It wasn't precise on the stack, but for unrelated reasons.  As far as 
work left to the programmer, I has created templates for new (which I 
thought at the time might get integrated into the compiler).  To use the 
precise heap scanning, all you had to do was:

class C {
     void* ptr;
     size_t integer;
}

void main() {
     auto instance = newTemplate!C();
}
