What about using a template class with a partial specialization that
is defined afterwards?

template <class A>
class T {
 A a;

int func() {
    return sizeof(T<void *>);

template <class A>
class T<A *> {
  A *a[10];

I think that all uses that change the meaning of any symbol after it's
defined is bad design or bad implementation. If you were to change the
ordering inherently, you'd have to give very explicit warnings or
errors on these kinds of situations (in particular, typedefs and
partial specializations).
