Yeap. You did catch me. And if you don't have "@intransitive 
const" or
C++'s mutable you can't save ref to the allocator within object:

struct RCExternal
{
     //alias allocator = theGlobalAllocator;
     auto allocator = &theGlobalAllocator; // assign mutable to 
immutable

     private void[] data;

     ~this () { allocator.decRef(data.ptr); }
}
