After converting Servo to Rust 0.6, I had to go an add a few Clones in libstd. If we decide not to automatically derive Clone then some kind of systematic pass on libstd and libextra will be necessary to make sure none are missing. Missing Clones in libstd and libextra are the worst offenders because not only do you have to add them, but every downstream consumer must upgrade Rust to get the change too. jack. _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
