I'm aware there have been a couple of similarly themed solutions, but here's mine nonetheless:

    #include <iostream>
    
    struct Plus {
      int x;
      Plus(int _x):x(_x){}
      Plus operator+(int _x) {
        return Plus(this->x + _x);
      }
      bool operator==(Plus _x) {
        return true;
      }
    };
    
    int main() {
      Plus x(0);
      std::cout << bool(x == x + 2); 
    }
