Funny note: Implementing e.g. a flexible observer pattern in Rust has the same ownership and lifetime problems. Usually this involves some weak reference, central broker, etc. So, that's really not only a language problem, but rather the result of the pattern / data structure involved. I.e. cyclic dependencies not being very nice once you have to think about lifetimes.
