Sometimes it is helpful to check whether we have a NULL python object, created via PythonCall.pynew(), e.g. to check if something has been initialized yet. (PyPlot needs this for lazy module loading, for example.) It might be nice to have a function like:

ispynull(x::Py) = PythonCall.getptr(x) == PythonCall.C.PyNULL

since this otherwise requires you access PythonCall internals.
