Slicing to convert pointers to bound arrays

[simendsjo]

I understand this is an unsafe operation, I just have a quick question.

Here, b points outside a's memory, so I get garbage.
        {
                int[] a = [3,3,3];
                auto p = a.ptr;
                auto b = p[0..3];
                assert(b == [3,3,3]);
                b = p[0..4]; // b == [3,3,3,?]
        }


When I do the same with a static array, I get 0. But this is just 
actually garbage, right? It might contain other data, and not always 0?

        {
                int[3] a = [3,3,3];
                auto p = a.ptr;
                auto b = p[0..3];
                assert(b == [3,3,3]);
                b = p[0..4];
                assert(b == [3,3,3,0]);
        }
