Python is criticised for the GIL preventing multiple threads running at once. Turns out that many languages don't support this kind of parallelism, including JS, PHP/Hack and OCaml (although multicore-ocaml is underway).

I really like pattern matching in Rust, but I find myself using it less and less.
`if let` and `let ... else` require substantially less indentation, and I often use them for Option values.
I don't miss this syntactic sugar in OCaml though. Maybe it's just because OCaml has a 2 space indent, unlike Rust's 4 space indent?
Coming from JS or Python, imports in Rust feel weird. They're entirely optional aliases for fully qualified symbols, which are always available.
I don't know of many other languages where you can just start using libraries. Java is the only one I can think of.
