It needs to be `array`? If we allow linked list each position can
"self append" to global list:

```
#include <functional>
#include <cstdio>

struct Node
{
    inline static const Node* first = nullptr;

    std::function<void()> callback;
    const Node* next;

    Node(std::function<void()> c) : callback{ c }
    {
        next = first;
        first = this;
    }
};


Node nameX = { []{ std::puts("test1"); } };
Node nameY = { []{ std::puts("test2"); } };

int main()
{
    auto f = Node::first;
    while (f) //this loop could be wrapped into "foreach" loop
    {
        f->callback();
        f = f->next;
    }
}

```

Dlls would be only problematic if you would be allowed to load and unload them.
It would probably need lot of mutex to guard updates.
