I'm highly curious about Rust as a potential introduction to systems programming. One thing that bothers me is the lack of proper classes. This seems to have become a trend among newer languages, as though traditional OOP is an outdated paradigm. I have yet to be convinced that this is a good move. The attempted justifications I've seen hand-wave about problems with OOP, "composition over inheritance," etc. Meanwhile, in the real world, 99% of production code is OO and the paradigm continues to do its basic job--helping programmers model domain objects. Older languages like JavaScript and PHP have made their OO constructs more robust over time, which suggests to me that in the end a critical mass of developers will always clamor for this easily understandable and productivity-enhancing paradigm over some theoretically pure alternative.
