Well that's reasonable. I guess I was trying to keep it so that python 
users could not instantiate the Creator in order to mirror the C++ side. 
It sounds that your proposed change to BPL would certainly eliminate the 
issue I was seeing. Either way, the removal of no_init will solve my 
near-term problems.

Thanks for you quick replies and help!
