Personally, I've had the opposite experience. Rust is one of the few languages that has proper support for algebraic data types and pattern matching, which I consider table stakes for a programming language. I know that's not what draws most people to Rust, and I'm also drawn to many other aspects of it, but it bothers me that most languages embrace product types but have little or no support for their categorical dual.
