The language keeps growing, with
- new features overlapping old features from previous standards without replacing them or deprecating them (function::copyable_function vs std::function, std::less<> key for transparent lookup in maps)
- new features not usable by the layman (coroutines ...)
- Cryptic syntax (reflection...)
- Stuff you are told not to use because of performance reason and that cant be fixed because of ABI (regex)
- Compile errors that are 1km long (no, concepts are not helping here, the 'nicer' message is still buried into a hot pile of template instantiation callstack).
It's easy to compare new and old languages, and saying older languages are wrinkly. Let's see how other shiny programming languages look like when they are 40 years old.
Sure, none is perfect and they have cruft and warts, but they are not such a mess as C++ is.
sudo-rs was pulling in 1M+ LOC as its dependency chain at one point. I believe they removed the biggest offenders, but I didn't check it recently.
