I'd appreciate a look at the updated library

https://github.com/boostorg/pfr and its docs https://apolukhin.github.io/magic_get/index.html

Any comments and feedback is welcomed!

Note that the last day for new libraries for Boost 1.75 is tomorrow (2020-10-21). PFR has a develop submodule, but no master submodule yet. I was waiting until you believe it is ready, and have ironed out all the issues on develop. If you want it included in the 1.75 release, and there are no objections from any reviewers, I can add the master submodule today. (It was already added to the in-progress release notes for 1.75, but that can be removed if you don't want to release it until 1.76). Glen
