Rust's lifetimes make it about the only language that gets shared-memory concurrency right. And I don't like the trend of pushing for message passing just because historically it was hard to do shared memory. The only thing I've found more convenient than that was software transactional memory in Haskell (monads and do notation working with it barely different than regular mutable memory), maybe by the next 10 years or so we'll get that in a mainstream language.
