I wrote the below code

    class LazyLoadingProxy(proxyForInterface(interface, '_original'), ):
        _cached_original = None
        def __init__(self):
            '\n                                                The    initializer    of    a    class    generated    by    ``proxyForInterface``\n                                                expects    the    wrapped    "original"    object    as    an    argument.        Overrride\n                                                that    here.\n                                                '
        @property
        def _original(self):
            if (self._cached_original is None):
                self._cached_original = loader()
            return self._cached_original
    return LazyLoadingProxy()

What's a good function header?
