Sounds exciting!

If you're referring to adjacency_list, then I can only say that
generative data structures pretty much always feel like
metaprograms... because they _are_ metaprograms.

Are you planning to move away from generative programming in BGLv2?

In what way does that make it "no good?"

For example?
