Rust is beautiful
I've invested some time to learn in detail about Rust, which means reading the excellent online book here . And it is beautiful. It makes me wish I could pause the world for a few years, to convert some 500,000 lines of C++ that exist under my purview into Rust, and continue from there. Rust seems to take all the little design lessons I've learned in 20 years of C++ programming, and consolidates them into one language: It's not best that everything is mutable by default, and const if the programmer points it out. It's healthier the other way around. The fundamental string type is a sensible, immutable string slice (in Rust, a &str ). This is great for zero-copy parsers, such as nom . Our code has had that for a decade – I named it Seq , or SeqPtr . C++ is adding std::string_view in C++17. Elegant built-in variant with pattern-matching (in Rust, this is an enum ). C++ is adding std::variant in C++17. Type traits solve the problems of abstraction and generics
