[New-bugs-announce] [issue4727] pickle/copyreg doesn't support keyword only arguments in __new__

[Erick Tryzelaar]

New submission from Erick Tryzelaar <idadesub at users.sourceforge.net>:

According to both of these bugs:

http://bugs.python.org/issue1398
http://bugs.python.org/issue4331

pickle can't pickle functools.partial objects. It looks the underlying 
reason is that objects that pickle can't handle objects with __new__ and 
keyword only arguments. To support this, would this require a new pickle 
protocol and a __getnewfullargs__ that returns a tuple and dict?
