Rust: fib

Rust is an interesting language. It is not a primitive one, like Go where we don't have ADTs, pattern matching and generics (but we do have Nils). And it's advertising as a safe and performant system language. Today is the very first day I'm looking at it. Let's "smoke" test it with Fibonacci :) Debug: 3.44 seconds, release: 1.66 seconds. This is not very impressive, but pretty fast indeed. C# - 1.26 D (DMD) - 1.3 F# - 1.38 Nemerle - 1.45 Rust - 1.66 Haskell - 2.8 Clojure - 9 Erlang - 17 Ruby - 60 Python - 120 It's very interesting how it'll behave in concurrent Fibonacci test. The compiler is quite slow: it takes 2-3 seconds to build this tiny program.
