- Everything is a proxy.
  - 3 layers.
    1. Check Sugarcube datastore.
      - Sugarcube datastore is set (or deleted) automagically whenever a value on the proxy is modified.
    2. Check Init datastore (also stores actual inited non-proxy objects).
      - Initialized with a data object containing key-value pairs.
      - can have nested create()s to init child objects (ie, a Person's Inventory).
    3. Check actual non-proxy object fields.
      - straightforward field return.
- All access, even in internal methods, is done through proxy.
  - Provide access to a proxy object called 'me', to replace 'this'.
  - Using 'this' is only acceptable in constructor.
  - This fixes the problem of object methods getting the wrong data depending on the inheritance hierarchy.
