Continuing the XKCD meme, and @mlange-42 previous efforts in finding what they want I've made another ECS library for Go.

It's doing code gen to get me the relationship and DSL like features I want. Still early (and don't read too much into benchmarks) but I'm pretty happy.

On a i7-12700H

Not sure you want to include as part of your benchmarks but thought @mlange-42 might be interested in an alternative approach. Thank you for you help in the past btw.

PS. I've also added the pathelogical flecs test for archetype vs sparse sets.
