yes, they are available as obj.__dtor() and obj.__postblit(); 
But...

No.

extern(C)
@trusted void printf(const char*);
struct Child {
         @safe ~this() { printf("child dtor\n"); }
}
struct Parent {
         Child c;
         @safe ~this() { printf("parent dtor\n"); }
}
void main() @safe {
         Parent p;
         p.__dtor();
}


parent dtor // this is the one from the p.__dtor
    // note it did NOT run child dtor
parent dtor  // the natural destruction from going out of scope
child dtor  // ...which also calls the child



So you'd have to loop through all members in a custom destroy 
function and call them yourself. Then attribute inference should 
work.
