2.1.8 Special Attributes

The implementation adds a few special read-only attributes to several object types, where they are relevant:

`__dict__`
  A dictionary of some sort used to store an object's (writable) attributes.

`__methods__`
  List of the methods of many built-in object types, e.g., `[].__methods__` yields `['append', 'count', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']`.

`__members__`
  Similar to `__methods__`, but lists data attributes.

`__class__`
  The class to which a class instance belongs.

`__bases__`
  The tuple of base classes of a class object.
