C++17: still using enums as constants? [duplicate]

Answer 1

The example that you give for using enum's can be rewritten as:

struct Point
{
    int x;
    int y;
};

struct Box
{
    Point p;

    int width;
    int height;
};

constexpr Box b = { { 1, 2 }, 3, 4 };

int f()
{
    return b.p.x;
}

Using strong types instead of int could even be a benefit.

For me this is more legible. I could even add some functions into that.
