Yes, that's the problem. The whole point is that the parser does not have 
enough context information to fully check for the number of template headers: 
there is an off-by-one possible error it has to allow. For instance:

template <> 
void A<int>::foo(void);

The correctness of this depends on whether A<int> uses an explicit 
specialization or not. So yes, we could unify this for 4.1.
