Spin-off compiler regression from:
https://d.puremagic.com/issues/show_bug.cgi?id=12000#c1

struct RefCounted(T)
{
    struct RefCountedStore
    {
        private struct Impl    // line 5
        {
            SharedInput _payload;
        }

        private void initialize(A...)(auto ref A args)
        {
            import core.memory;
        }

        void ensureInitialized()
        {
            initialize();
        }

    }
    RefCountedStore _refCounted;

    void opAssign(SharedInput rhs)
    {
    }

    int refCountedPayload()
    {
        _refCounted.ensureInitialized();
        return 0;
    }

    int refCountedPayload() inout;

    alias refCountedPayload this;
}

struct SharedInput
{
    Group unused;
}

struct Group
{
    RefCounted!SharedInput _allGroups;  // line 45
}

void main() {}


Output:

test.RefCounted!(SharedInput).RefCounted.RefCountedStore.Impl unable to resolve
forward reference in definition
