So if I have a module which relies on having internal data being set from outside, then, even though the program only ever has one instance of the module, different runs, say test and production, would require different internal data and thus different instances. Therefore a class seems more appropriate and it is more obvious to me how to initialise the objects (e.g. by having the some main function which can read command-line arguments and then just pass the arguments to the constructor. I suppose that the decisive aspect is that my module needs initialisation and thus should to be a class. Your examples in the other posting of the modules 'math' and 'string' are different, because they just contain functions and no data.
