@dataclass
class Person:
    name: str
    age: int

@dataclass
class Car:
    passengers: List[Person]

# Load some simple data types.
data = {'passengers': [{'name': 'Alice', 'age': 21}, {'name': 'Bob', 'age': 22}]}


# Create a schema for the Car class.
schema = desert.schema(Car)

# Load the data.
