My project contains a lot of classes, a bunch of which can be described by XML files. Don't worry, it's not the logic or implementation in XML. It's a game, and an example would be that a game tile can be defined in XML, the image file, animation frames, etc. I'm going to end up having a bunch of functions that look like this: public ...

Pickle fails (for example on module.MyClass.foo) stating it cannot be pickled, as module.foo does not exist.

I am wondering about the the following piece of Java code: "System.out.println". I am right about this: "System" is a static class. ".out" is a method of class "System".
