You can get the dynamic size of an object using
`typeid(base).initializer.length`.
Base base = new Derived;
assert(__traits(classInstanceSize, Derived) ==
typeid(base).initializer.length);

I implementing ref counted pointer with support for weak
pointers. Problem was that expired weak pointer can point to
already destroyed data => typeid() no longer work or ref type is
extern(C) class => typeid() doesn't work.
