Drawing d;
d.add(new Circle);
d.add(new Square);
d.add(new Line);
Plan p;
p.push(new Line);
p.push(new Square);
p.push(new Circle);
Schematic s;
s.push_back(new Square);
s.push_back(new Circle);
s.push_back(new Line);

new Circle, new Square, new Line
};

// allow them to be treated generically:
cout
