Disabling opAssign in a type disabled all the opAssigns of an aliased type?

I could have sworn I tested this before I wrote that it's a bug:

struct A {
     void fun(int) {}
}
struct B {
     A a;
     alias a this;
     @disable void fun(float);
}

void main() {
     B b;
     b.fun(3);
}

I was surprised to see it work, as I also thought it'd be a 
hijacking issue. Turns out, it doesn't actually work. I must have 
made a typo when I tried it. Ah well.
