I think this should work now. Unfortunately http://buildbot.rust-lang.org is down, so I can't confirm. Can it be retried again? |

This patch series changes a handful of vec functions to return references instead of copies. The one downside with making this change is that these functions aren't usable in a couple cases now due to some purity complaints. For example, this [change](erickt@c31e81a#L1R87). I couldn't figure out a way to get `last` to work on a `@mut ~[...]` type, so I ended up having to use `*crate_cache[crate_cache.len() - 1].metas`.
