The python pickle module is an interesting and helpful module. It offers an easy way to save an load your own python datastructures (classes) without having to design your own file format and implement import and export procedures. This text is about what can happen if you try to pickle an instance of a class you defined in the same (script) file. A scenario in which this could happen: you have a module defining some classes with save and load functionality through the pickle module and beside being able to import that module in other python scripts, you also want to be able to run it as a standalone script. (As a sidenote it could be important to mention that python version 2.4.2 is used for these "experiments".)
