About method chains and Lisp: in Clojure you can write code very similar to that using threading macros:

    (-> (args)
      (skip 1)
      (next)
      (unwrap)
      (length))

I really do think that for long "Java-esque" chains like this, Clojure has the right idea, I think it's very readable.

This isn't really related to the Lisp to Rust transpiling thing though.
