Should I cheer or cry? FYI, I'm crying. Let's have a look a basic thing
like creating a Window. I'm taking the Samples/ rocks_in_space as an
example as that seems to be as close as it gets to "a simple 2D game". So
we are creating a window:
Somebody must have lost their mind, it's just raw Win32-code (and
corresponding Linux x11 code (Wayland anyone? I'm on Fedora)).

Now let's see how we do that in SFML:

#include <SFML/Window.hpp>
int main()
    sf::Window window(sf::VideoMode(800, 600), "My window");

    // run the program as long as the window is open
    while (window.isOpen())
        // check all the window's events that were triggered since the
last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)

    return 0;

Just to be clear we did not just do that, we created a window, an
event-loop and a functioning "close that window button". This code will run
as is on Windows, Linux and OSX (each in its proper native look).

But, on the bright side, I'm happy that potentially P0267 will be
standardized, then SFML can keep on being developed as is and can progress,
introduce breaking changes if deemed useful and will not be stuck in a 3
year update cycle.
