| That would be horrible for generic code.
Care to explain why?
| What are the requirements
| on the T parameter of this class template?
|
| template <class T>
| struct Der : T
| {
| template <class U>
| void f(U x)
| {}
| };
Should those requirements be different from those for
template<class S>
struct Der : S
{
template<class U>
void f(U x)
{ }
};
?
