Composition Example

Demonstrate the use of Compostion of Atom objects.

1. If the class has not been declared, use a ForwardTyped
   • Note the use of lambda, because "Person" is not yet defined
2. A Typed object can be instantiated three ways:
   • Provide args, kwargs, or a factory in the definition
   • Provide a _default* static constructor
   • Provide a pre-created object in the constructor

Tip

To see this example in action, download it from composition <../../../examples/api/composition.py> and run:
