Static methods and variables are useful when you want to share
information between objects of a class, or want to represent something
that's related to the class itself, not any particular object.
For some reason, PHP allows you to call non-static and static methods
interchangeably, which as far as I can see, makes *no* sense at all,
neither from a semantic nor a programmatic point of view.
