Not required. The argument is typed statically, and it throws TypeError if a wrong argument is specified.
In [5]: Device.set_default({})

TypeError: Argument 'device' has incorrect type (expected primitiv._device.Device, got dict)

get_cpp_something may return NULL and NULL is acceptable by C++ APIs (if they received NULLs, it is replaced to the C++-side default objects). This may confuse the overall behavior.
It is good to add some Python-side functions get_default_or_die, or adding an option to get_default to raise an exception if the Python-side default object is null.

Fixed. get_default() checks default object now.

Related to #39
This branch holds default objects in the python module instead of using set/get_default() of the core library.
I checked that it works fine on Windows 10.
