Compiler Error C3858

Error Message

'type': cannot be redeclared in current scope

The type cannot be declared twice in the same scope.

The following sample generates C3858:

// C3858.cpp
// compile with: /LD
template <class T>
struct Outer
{
   struct Inner;
};

template <class T>
struct Outer<T>::Inner;   // C3858
// try the following line instead
// struct Outer<T>::Inner{};
