matches() is not supported for associations. It could be supported by using an equals operator (#199), but that would make the core package depend on the operator package, resulting in a circular-dependency between those two packages. By dropping this method, an operator can be used consistently for all types of model elements (instead of operators for associations and matches() for other element types).
