The deprecation shim created by Doug turns out to be rather useful. It emits a warning when an global (attribute of a module) is referenced but that global has been moved to another module. This update makes the following changes to the shim: - Rename it to _MovedGlobals to better describe what it is a debtcollector for. - Use inspect to get the original reference and to check that _MovedGlobals is called from the last line of a module. - Save the old reference automatically in the instance to prevent it from getting garbage collected. - Beef up the _moved_global() method for moving/renaming individual globals, allowing it to move and rename or rename in place.
