     The `class Meta` concept in iommi is slightly different from how it's used in Django. In iommi any argument to the constructor of a class can be put into `Meta`. In fact, ONLY valid arguments to the constructor can be set in `Meta`. In our example above we set `title` and `rows`. We can also instead set them via `Meta`:
