"""Demonstrate how SQLAlchemy 1.2 breaks pickling of ORM objects.

This somewhat-contrived example shows a query scenario where:

- We have an object (Garply)
- It is related to a table of Foos
- Foos uses single-table polymorphism to hold multiple types
- We query a Garply and eager-load some of its Foos
- We then pickle this Garply and its Foos for hand-off to some other process.
  Since it already has its Foos loaded, we know it won't need further database
