Note that this is based on `wrapt <https://pypi.python.org/pypi/wrapt>`_'s ObjectProxy with one big change: it calls a function the first time the proxy object is used, while `wrapt.ObjectProxy` just forwards the method calls to the target object.

In other words, you use `lazy-object-proxy` when you only have the object way later and you use `wrapt.ObjectProxy` when you want to override few methods (by subclassing) and forward everything else to the target object.
