// This is nasty: if we allowed the injected-class-name to be looked as a
// qualified type, then the following code would be well-formed. Basically
// the last line is defining the static member (with redundant parenthesis).
// Instead, it should be rejected as a malformed constructor declaration.
template <class T> struct A {
template <class T2> A(T2);
static A x;
};
template<> template <> A<char>::A<char>(char);
template<> A<int>::A<int>(A<int>::x); // { dg-error "" "this is an invalid declaration of the constructor" }
}
// But DR 318 says that in situations where a type is syntactically
// required, lookup finds it.
struct C
{
C();
typedef int T;
};
struct C::C c;

struct D: C::C

// And if lookup doesn't find the injected-class-name, we aren't naming the
// constructor (c++/44401).
