LazyObject
----------

``LazyObject`` is an undocumented utility class used for lazily wrapping other
objects of unknown type.  In Django 1.1 and earlier, it handled introspection in
a non-standard way, depending on wrapped objects implementing a public method
``get_all_members()``. Since this could easily lead to name clashes, it has been
changed to use the standard method, involving ``__members__`` and ``__dir__()``.
If you used ``LazyObject`` in your own code, and implemented the
``get_all_members()`` method for wrapped objects, you need to make the following
changes:

 * If your class does not have special requirements for introspection (i.e. you
   have not implemented ``__getattr__()`` or other methods that allow for
   attributes not discoverable by normal mechanisms), you can simply remove the
   ``get_all_members()`` method.  The default implementation on ``LazyObject``
   will do the right thing.

 * If you have more complex requirements for introspection, first rename the
   ``get_all_members()`` method to ``__dir__()``.  This is the standard method,
   from Python 2.6 onwards, for supporting introspection.  If you are require
   support for Python < 2.6, add the following code to the class::

       __members__ = property(lambda self: self.__dir__())
