alt Hacker NewsThe last time I worked meaningfully with C++ was back in 2013. Now that I write mostly Rust and TypeScript, I'm amazed by how C++ has changed over the years!
Regarding the "auto" in C++, and technically in any language, it seems conceptually wrong. The ONLY use-case I can imagine is when the type name is long, and you don't want to type it manually, or the abstractions went beyond your control, which again I don't think is a scalable approach.
Type inference is actually very useful you just need to have the right amount, too little and most of your time is spent on bureaucracy, too much and the software is incomprehensible.
In both Rust and C++ we need this because we have unnameable types, so if their type can't be inferred (in C++ deduced) we can't use these types at all.
In both languages all the lambdas are unnameable and in Rust all the functions are too (C++ doesn't have a type for functions themselves only for function pointers and we can name a function pointer type in either language)
