:class:`~django.db.models.query.QuerySet`, ``RawQuerySet`` doesn't
implement all methods you can use with ``QuerySet``. For example,
``__bool__()`` and ``__len__()`` are not defined in ``RawQuerySet``, and
thus all ``RawQuerySet`` instances are considered ``True``. The reason
these methods are not implemented in ``RawQuerySet`` is that implementing
them without internal caching would be a performance drawback and adding
such caching would be backward incompatible.
