But if I understand comment #3 correctly, then the workaround originally 
proposed for this PR, namely
----------------------------
template <int dim> class X {};

template <class T> class Y {
    static const unsigned int dim = 1;
    X<dim> f();
};

template <class T>
X<Y<T>::dim> Y<T>::f() { return X<dim>(); }
---------------------------
no longer compiles? 

I don't have current sources around here, but this worked with 4.3.2.
If it doesn't work with mainline, then this *would* be a regression.
Can someone check?

Thanks
 W.
