It's common to have to call a class instances's method more than once. If
that function is expensive, then doing so can be wasteful.
Using the ``@cached_property`` decorator saves the value returned by a
property; the next time the function is called on that instance, it will return
the saved value rather than re-computing it. Note that this only works on
methods that take ``self`` as their only argument and that it changes the
method to a property.

Certain Django components also have their own caching functionality; these are
discussed below in the sections related to those components.
