Worst thing about 2020 C++

Oh, wait=E2=80=A6   With that reasoning, you could argue that C++ should have stopped evolving with "C with classes" around 1980 ...   /Jorgen   -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o .

How do I know I can make my code better by applying some new language feature? There are countless C programmers implementing linked lists right now; we'd just use a std::vector and not even notice.   I want new language features to fall into the classes: A - Major and really useful to many people. B - Minor, easy to adopt. C - Fringe features, easy to ignore.   I haven't investigated coroutines yet; I hope they are in class A.   /Jorgen   -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o .

incompatible types in assignment

Some of this indicates an influence from Java. If you know Java, you need to forget it while programming in C++.   If you want to map identifiers to obfuscated identifiers, I recommend an implementation based on std::unordered_map.   /Jorgen   -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o .
