# So here is how this baby works:
# Reload the module.

# also in the new module.
# Add an __getattribute__ or __getattr__ method to those classes that are
# present in the new module. This method will, when called, change
# the __class__ of the instance to point to the new class.
# Change the func_code, func_defaults, and func_doc of any functions or
# methods or generators we run across, just in case someone is holding
# a reference to them instead of calling them by name.
