Thanks for the article! As someone who writes a lot of Rust/JS/Wasm FFI it gave me some good food for thought :)

Yes! Mutexes are much nicer in Rust than a lot of languages, but they're still much too low-level for most use-cases. Ironically Lindsey Kuper was an early contributor to the Rust project and IIRC at roughly the same time started talking about LVars [1]. But we still ended up with mutexes as the primary concurrency mechanism in Rust.
