Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 14:18:55 +02:00			`// run-pass`
Add `#![allow(..)]` for a slew of lints of migrated run-pass tests, to silence stderr output. 2018-08-31 15:02:01 +02:00			`#![allow(stable_features)]`

Allow use of `[_ ; n]` syntax for fixed length and repeating arrays. This does NOT break any existing programs because the `[_, ..n]` syntax is also supported. 2014-12-20 15:20:51 +13:00			`let x: [u64; 3] = [1, 2, 3];`
Make `sum` and `product` inherent methods on `Iterator` In addition to being nicer, this also allows you to use `sum` and `product` for iterators yielding custom types aside from the standard integers. Due to removing the `AdditiveIterator` and `MultiplicativeIterator` trait, this is a breaking change.
