This RFC patch series is a first stab, at adding some syntactic sugar making it more plessant to implement non-trivial dual-stack configurations, like https://bgpfilterguide.nlnog.net/ I'm not completely happy with the naming at this stage, but I want to get this series out before 36C3 ends. Looking forward to your feedback.
