I assume he means multi-dimensional arrays:

    std::array<std::array<int, 3>, 5> array_of_ints;
    int c_style_array[5][3];

But the C-style array is more readable, so I am not sure what the complaint really is about.

No, I think he means that for any given type, you can wrap it in an array the same way. Your example is demobstating that it even works recursively, but it works in the simple case too by wrapping "int" in an array to get an array of ints. There's no need to jump back and forth between each side when adding new layers (which gets described as a "spiral", but in a single line of code, I'd argue that it's really just jumping back and forth, and that's why it's annoying to people like the parent commenter and I)

[uecker]

If I would add another array, it would look like:

int c_style_array[2][5][3];

There is also no jumping back and forth. C declarations are also recursively constructed. One can complain about the irregularity of pointers syntax.

Yes, if you only use arrays, then it doesn't make things confusing. The point they were making (as I understand it) is that putting a pointer inside std::array doesn't change the way you have to read it, which is not the case for C arrays.
