After fixing bug8982, following code reports a lot of errors, but they are
pointless.

---
import std.traits;

struct Vector
{
    float x,y,z,w;
    immutable Vector one = Vector(1,1,1,1);
}

void func(int x = 10, ref const Vector v = Vector(1,1,1,1));

version(A)
pragma(msg, ParameterIdentifierTuple!func);
version(B)
pragma(msg, ParameterDefaultValueTuple!func);
