...     __slots__ = ('type', 'weight')
...
...     def initialize(self, type, weight):
...         self.type   = str(type)
...         self.weight = float(weight)
...
>>> class Pie(jsonable.Type):
...     __slots__ = ('fruit',)
...
...     def initialize(self, fruit):
...         self.fruit = [Fruit(f) for f in fruit]
...
...
>>> pie = Pie([Fruit('apple', 10.3), Fruit('cherry', 2)])
>>>
>>> doc = pie.to_json()
>>> doc
{'fruit': [{'weight': 10.3, 'type': 'apple'}, {'weight': 2.0, 'type': 'cherry'}]}
>>>
>>> pie == Pie(doc)
True
