Example Code: struct Shape { void draw(); int area(int x, int y); };

make_trait(Shape, draw, area);

int main() { auto circle = Circle(); auto square = Square(); // NOTE: all of this is strictly checked, so if you are creating // a trait out of a Object, the object MUST implement all the trait functions auto t0 = trait<Shape>::make(&circle); t0.draw();

    auto t1 = trait<Shape>::make(&square);
    t1.draw();

    // Another thing to be kept in mind is trait<T> is just like a View
    // It DOES NOT OWN anything, so you are the one making sure the data
    // pointer is valid
  
    auto array = std::array{t1, t0};
    for (auto& shape : array) {
        std::cout << shape.area(2, 3) << std::endl;
    }    
}
