Programmatically output lyrics on a tee-shirt

Some years ago I re-wrote the lyrics of a song as a JS script. I ordered a tee-shirt with this "art" of mine (I actually find it quite beautiful 😅).

But everytime someone looked at my tee-shirt, they would ask me if it really means or does something. I would answer "no, it doesn't work, it's just a representation".

But now, I've implemented it!

I chose C++ to be able to overload operators exactly as I wanted... My goal was to not change anything about this source code, which I designed without knowing I would implement it.

So in the main.cpp file, all I have is the following:

#include "logic.cpp"

int main()
{
    /**
     * Guess the song... 😌 😎
     */

    imagine(!heaven) == "easy";
    us.below = !hell;
    us.above = sky;
    imagineAll("living for today");

    imagine(!countries) != "hard";
    (kill || die).reasons.length == 0;
    religion = undefined;
    imagineAll("living life in peace");

    chorus(); //🎵🎶

    imagine(!possessions) ? "😀" : "😥";
    need(greed || hunger) == false;
    men.reduce([]() { return "brothers"; });
    imagineAll("sharing all the world");

    chorus(); //🎵🎶
}

All the logic is included in another file.

As you can see, the only differences are the double quotes for the string literals and the syntax of the lambda expression. Apart from that, it's the exact same thing as my tee-shirt.

Here's the output of the program, without any hardcoding:

So, did you guess the song?
