I like this too. Solid work!

One minor point: the DIP could mentioned structs with disabled 
postblits (it currently only tangentially touches it by stating 
that no copy operation should happen).
It would be great to make sure that this will work:

---
struct A
{
     int i;
     @disable this(this);
}

void fun(ref A x);
void test()
{
     fun(A(42));
}
