in favor of `move`. This breaks code that used `move` as an identifier, because it is now a keyword. Change such identifiers to not use the keyword `move`. Additionally, this breaks code that was counting on by-value or by-reference capture semantics for unboxed closures (behind the feature gate). Change `ref |:|` to `|:|` and `|:|` to `move |:|`. Part of RFC #63; part of issue #12831. [breaking-change]
