- from the class's constructor.

- However, the properties of that meta object are only shallow-cloned,
- so if a property is a hash (like the event system's `listeners` hash),
- it will by default be shared across all instances of that class.

- This method allows extensions to deeply clone a series of nested hashes or
- other complex objects. For instance, the event system might pass
- `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
- walk down the keys provided.
-
- For each key, if the key does not exist, it is created. If it already
- exists and it was inherited from its constructor, the constructor's
- key is cloned.
-
- You can also pass false for `writable`, which will simply return
- undefined if `prepareMetaPath` discovers any part of the path that
- shared or undefined.

- Second, as we do not have the luxury of in-VM iteration, we implement a
