With opAddRef/opRelease class does respondible for its
dealocation and its own payload so breaks SOLID's single
responsibility principle. As for me better design will be to do
it closer to C++'s shared_ptr.
e.g:
// maybe with @arc
struct RefCounter(T)
{
void opAddRef();
void opRelease();
ref T obj;
ref size_t count;
}
}
RefCounter!Widged myRefToWidget;
RefCounter with default ctor/dtor. opAddRef and opRelease is for
compiler optimtimisation and elimination of redunadant ref
counter increment/decrement.
