How too wirte this: addPoint({4,5}, {4,6})

You have to write `Point(4, 5)`. The advantage is we don't need to deal 
with the complexity of C++ overloading rules.

In this case, arrays are better but only if you don't define a 
constructor, which you don't need for simple types like Point below:

struct Point {
     int x;
     int y;
}

void main() {
     // The type is explicit on the left-hand side
     Point[] points = [ {1,2} ];
}
