> I wonder if C++ has some hairy concepts and syntax today on par with Rust's more difficult parts.
… … … … Unqualified name lookup has been challenging in C++ since even before C++11. Overload resolution rules are so painful that it took me weeks to review a patch simply because I had to back out of trying to make sense of the rules in the standard. There's several slightly different definitions of initialization. If you really want to get in the weeds, starting playing around with std::launder and std::byte and strict aliasing rules and lifetime rules, and you'll yearn for the simplicity of Rust.
C++ is the absolute most complex of any of the languages whose specifications I have read, and that's before we get into the categories of things that the standard just gives up on.
