Show me some explicit examples what you want to do with it in the
templates.
Sure. I often use static methods to share functionality between code and templates. These methods _could_ be rewritten as modifiers or functions for the templates, but that would make the methods inconvenient to use in regular PHP code.
Or I would have to write a wrapper as a modifier or function, which is also inconvenient.
Simple example: Location::getZipCode($city);
Which could be nicely used either directly in the templates as {Location::getZipCode("Los Angeles")} or in PHP code for further processing.
