For instance, it could be implemented to allow you to replace the dict attribute in a module with a user provided object which implements the dictionary protocol. I'd like this, as well, although my use case is different: I'd like to be able to deprecate attributes in a module. That is, if I have: foo.py: SOMECONSTANT = 5 I'd like to be able to do something such that any time anyone accessed foo.SOMECONSTANT, it'd emit a DeprecationWarning.

Agreed, this would be another nice feature to have.

I've did something similar a time ago for PyGTK aswell, while less elegant than your proposed solution, it seems that it's working fairly well:

DeprecatedConstant can be found here: http://cvs.gnome.org/viewcvs/pygtk/gtk/deprecation.py?view=markup
