How can I translate this line?

SymPy.PyCall.PyNULL()

I am trying to convert SymbolicControlSystems.jl to use this library.

That should become

SymPyPythonCall.PythonCall.pynew()

(It is used to create a null object that is written to later in an _init_ function.)

But, I'm in the middle of trying to consolidate the SymPy and SymPyPythonCall code bases into a package that I hope to begin registering today (SymPyCore). I don't expect any breakage, but if that package reaches into some internals, there may be. In the new case, you should be able to write SymPyPythonCall._pynull()

Thank you!
