By fixing issue 8339, invalid accessing to nested struct shows compile error.
But, some cases are still accidentally accepted.

void check(T)()
{
    // nested struct constructions outside valid frame scope
    T t1 = T();
    T t2 = T(1);
}

void main()
{
    struct S
    {
        int n;
        void foo(){}
    }
    check!S();
}

What exact rules does the language define for these function-nested types? It
seems arbitrary that some things are allowed while others are not, for example
this works:

void check(T)()
{
    T t = T.init;
    t.foo();
}

void main()
{
    struct S
    {
        int n;
        void foo(){}
    }

    check!S();
}
