Very newbie question coming up :)How does D mark null values for classes? `c is null` returns true, but `&c` isn't 0. So how does D know `c is null`? class C {} C c; assert(c is null); assert(cast(size_t)&c == 0); // fails.
"&c" is address of reference, no class instance. I don't know if there is a way to get a pointer to class instance in D but I am not aware of one.
