Thank you.

No, this is entirely new to me. I had a quick look on it and it definitely 
seems to be a possible solution. Because it is a quite broad topic and there 
are different things to take care of, do you have any particular topics that 
are covering solution to my intention (Actors, Operators etc.)?
I am concerned actually about the type that such a combination of predicates 
might have, because the type has to be provided to the filtered_graph-
template...

Best,
