Simple question on compilers and syntax rules
In general, LALR parser generators are more difficult to work with than RD parser combinators. Instead of flex and bison, I'd recommend checking out Boost.Spirit or lexy.

How often do you use these keywords ?
lexy has something like std::bind with a way to specify fallback values for the placeholders if the arguments aren't provided: lexy::_1.or_default(fallback)

[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 I’m 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:

scnlib (scanf for modern C++) - version 1.0 released
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 :)
What are some alternatives?
When comparing lexy and scnlib you can also consider the following projects:
PEGTL - Parsing Expression Grammar Template Library
C++ Format - A modern formatting library
parser-demo - Good source layout with Flex and Bison
gainput - Cross-platform C++ input library supporting gamepads, keyboard, mouse, touch
gadgetron - Gadgetron - Medical Image Reconstruction Framework
cpp-peglib - A single file C++ header-only PEG (Parsing Expression Grammars) library
json_struct - json_struct is a single header only C++ library for parsing JSON directly to C++ structs and vice versa
