      Nobody added those new concepts to Rust for fun. They were added because they were necessary to make a memory-safe, modern, and fast language.

      Really? We can’t have basic classes because of memory safety?

      I thought you were complaining about too many features, not too few.

      (In particular, not having classes is a weird argument for using C over Rust!)

      If I’m going to have to mess around with something confusing I can either use C++ or just write functions. I don’t want the overhead of learning a bunch of weird new syntax to do a little project.

      What parts of the syntax do you consider weird?

      I ran into a bunch of documentation convincing me to learn about how to use traits as a way to make what seems to be a very limited class system. I’m sure it all makes sense, it’s just annoying.

      I mean…you can also use functions the same way you could in C. Classes aren’t in the language not because of functional purity, but because most systems programmers complained.

      In particular you can use structs of function pointers. I do it sometimes. But yeah, about classes, there were systems people who were ready to fork the language to remove them if they got added. (Not that they were seriously considered.)

      And this is the problem. You can’t take something people are comfortable with and make it safe and performant, you have to cater to a lot of people’s other opinions.

      I mean, we did. It’s just that that thing was more C than C++. (It’s funny, we get accused of being too C++-like probably more often. Kind of refreshing to hear criticism from the other direction, to be honest) :)

          I represent the lazy contingent of people who want the existing feature set with the absolute minimum overlay of new features necessary to get memory/thread safety.

          Existing feature set of C++, not C? Because there are plenty of people who want that, but with C.
