Yeah, but parsing format strings in runtime induces an overhead, and doing it in compile time is not trivial, and I’m not sure ClearIO is worth the trouble, since it turns out scnlib exists.

The code is rather nice (in my biased opinion) and makes heavy use of a couple of libraries like scnlib and [Eigen](eigen.tuxfamily.org/). Some things could probably be more optimized but I mainly focused on conciseness. I hope this is useful and I can explain my thought process further if you have any questions.

I've found https://github.com/eliaskosunen/scnlib but haven't tested it. Maybe that suits your needs for 2.

I had a user enum like enum class Color {Red, Green, Blue}; that I wanted to add serialization support for. Following the docs (https://scnlib.readthedocs.io/), after some tweaks I arrived at the following:

Thanks for the comment, I made an issue tracking this: https://github.com/eliaskosunen/scnlib/issues/51

I am using some modern libraries: scnlib fmtlib Eigen and usually abuse lambdas :)

I hope we see this in C++26 as optional mode i.e. #safe and #unsafe and same for #impdef or so.

C++23 is done. But C++ is not! In this talk, the author shares his personal perspectives on an ongoing and very active evolution of C++, updates on his cppfront experimental compiler, and why compatibility is essential to the further success of the C++ development.

But his side project at Microsoft didn't gain traction with gcc, clang, etc and everybody else in the industry. So at this point, the C++ committee will be perceived as "so far behind" ... because there's nothing for them to vote on.

C++ has major flaws that cannot be rectified without serious breaking changes. With that said, Herb has been experimenting with a new cpp frontend with sane defaults [1].

In my opinion, the world is on standby until Anders Hejlsberg feels like tackling a modern, next generation systems language.
