Static properties
=================
The section on :ref:`properties` discussed the creation of instance properties
that are implemented in terms of C++ getters and setters.
Static properties can also be created in a similar way to expose getters and
setters of static class attributes. It is important to note that the implicit
``self`` argument also exists in this case and is used to pass the Python
``type`` subclass instance. This parameter will often not be needed by the C++
side, and the following example illustrates how to instantiate a lambda getter
function that ignores it:
.. code-block:: cpp
py::class_<Foo>(m, "Foo")
.def_property_readonly_static("foo", [](py::object /* self */) { return Foo(); });
Unique pointers
