> We would like to have correctness checks for Python source strings when we 
> construct PythonCallableSource object in Java SDK.
> We might launch Python subprocess in PythonCallableSource.of method and call 
> eval function to easily check syntactic correctness. Python parser module 
> from Jython library could also be helpful.
