It's almost certain that every instance from non-__main__ module
pickles correctly b/w python and ipython.
In %run, the following works correctly w/ fm2.diff patch:
self.a = 10
c = C()
However, that one fails in interactive prompt because InteractiveShell
thinks it's in FakeModule (iplib.py line 317) and with fm2.diff, the
user_ns != FakeModule.__dict__ and unpickle fails with:
/usr/lib/python2.3/pickle.py in find_class(self, module, name)
1139 mod = sys.modules[module]
-> 1140 klass = getattr(mod, name)
1141 return klass
AttributeError: 'FakeModule' object has no attribute 'C'
It's a hard call, but I guess this is functionality we *could* afford
to lose, esp. if it fixes inspect.py problems. I'll still try to make
this work though.
