C++17 Optional Initializer Chaos

C++17 added optional initializers to if statements. Of course, since you can put declarations there, this lets you define classes in the condition of an if statement. if (struct { operator bool() { return true; } } b; b) { std::cout << "🙃"; }

A programming meme shows a dark-mode social media post explaining that C++17 allows declarations, including a local struct with a conversion to bool, inside an if statement. The joke is that this technically valid feature enables absurdly overcomplicated code, so the program prints an upside-down face as a reaction to the language's complexity.
