    Python ``@property`` decorator, but it puts the result of the method it
    decorates into the instance dict after the first call, effectively
    replacing the function it decorates with an instance variable.  It is, in
    Python parlance, a non-data descriptor.  An example:

    .. code-block:: python

        from pyramid.decorator import reify

        class Foo(object):
            @reify
            def jammy(self):
                print('jammy called')

        class Foo(object):

            def jammy(self):
                print('jammy called')
