[C++20] ClearIO library (unfinished)
Yeah, but parsing format strings in runtime induces an overhead, and doing it in compile time is not trivial, and Iām not sure ClearIO is worth the trouble, since it turns out scnlib exists.

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:

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

As always parsing the input takes most of the space. I did not bother writing my own loops to fill the diagonals and I used Eigen instead - github
