Well I asked in the python-dev list to see if this is part of python or not. GvR the former dictator says it's 
documented in stdtypes so is OK (part of the standard library). I'll take his word for it and continue to use these 
optimizations. At least they're findable through the __self__ usage so fixing won't be a problem when/if they are found 
to be bad.

Thanks again for the report
