give 1.0.2 a try since we adjusted some things regarding
__declare_first__ and __declare_last__. Further than that it depends a
lot on what your basic "Base" setup looks like, mixins in use,
extensions like AbstractConcreteBase, stuff like that. Any details you
can share would help.

I'm trying to upgrade from SA 0.9.8 to 1.0.1 and getting a traceback.
I'm not sure what's going on here, but the declarative setup is
obviously not happy with something. (On 0.9.8, everything runs fine,
so I've obviously run afoul of something new/different/fixed.)

AttributeError: 'NoneType' object has no attribute 'class_manager'
This gets fired off on every ORM class, so I'm guessing the cause is
somewhere deeper in our code. Any thoughts on what I might look for to
find the cause?
