<pre>Sample code:
template<class V>
struct B
{
template<class T>
T f() { return T(); }
};
template<class V>
struct D : public B<V>
{
typedef B<V> base;
using base::f;
template<class T>
void f(T &v) { v = f<T>(); }
};
int main()
{
int n ;
D<void>().f(n);
}
Error message:
14 : error: no matching member function for call to 'f'
void f(T &v) { v = f<T>(); }
^~~~
20 : note: in instantiation of function template specialization 'D::f'
requested here
D<void>().f(n);
^
14 : note: candidate function template not viable: requires single argument
'v', but no arguments were provided
void f(T &v) { v = f<T>(); }
^
With GCC this works well. I suppose using-declaration must bring all
identifiers from base class.</pre>
