My AoC2021 solutions in C++
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.

what annoys you most while using c++?
I've found https://github.com/eliaskosunen/scnlib but haven't tested it. Maybe that suits your needs for 2.

The Year is 2022 and the Standard is C++20; what is your preferred way to do Text I/O?
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:
