I have in the past wondered about creating a kind of graphical debugger, that rendered representations of all the objects in globals and/or locals, to give you a visual representation of your variables and their states. Would this be a valid use case to try and look up the variable names which reference various in-memory objects? -- http://mail.python.org/mailman/listinfo/python-list
