> Currently, the CEP library only supports a Java API to specify complex event 
> patterns. In order to make it a bit less verbose for Scala users, it would be 
> nice to also add a Scala API for the CEP library. 
> A Scala API would also allow to pass Scala's anonymous functions as filter 
> conditions or as a select function, for example, or to use partial functions 
> to distinguish between different events.
> Furthermore, the Scala API could be designed to feel a bit more like a DSL:
> {code}
> begin "start" where _.id >= 42 -> "middle_1" as classOf[Subclass] || 
> "middle_2" where _.name equals "foobar" -> "end" where x => x.id <= x.volume
> {code}
