My point was that any (new) feature introduces its own problems... As I said, I'll wait and see what Rust users have to say after a year or two.

Except, as it was pointed out, this is not a new feature. It has been around in many languages way before Rust.

You don't have to wait a year or two, check what the experience of users of languages such as Scala, Haskell, F#, and OCaml has been like.
