Put the result of a method which uses this (non-data) descriptor decorator
in the instance dict after the first call, effectively replacing the
decorator with an instance variable.
It acts like @property, except that the function is only ever called once;
after that, the value is cached as a regular attribute. This gives you lazy
attribute creation on objects that are meant to be immutable.
Taken from the `Pyramid project `_.
To use this as a decorator::
@reify
def lazy(self):
...
return hard_to_compute_int
first_time = self.lazy # lazy is reify obj, reify.__get__() runs
second_time = self.lazy # lazy is hard_to_compute_int

This is a decorator which can be used to mark functions and classes as
deprecated. It will result in a warning being emitted when a deprecated
function is called or a new instance of a class created.
In case of classes, the warning is emitted before the __new__ method
of the decorated class is called, therefore a way before the __init__
method itself.
