Rust Compiler Performance Triage

总的来说，编译器性能提升的一周，只有一次适度的退步。退步的 change 对bootstrap speed由显著的改善，更易于维护。

分诊人 @rylev. 修订范围：f1c47c..301ad8a

1 次退步，5 次改进，0 次混合，0 次汇总

Quote of the Week

最后，我觉得有必要揭穿对抗 the borrow checker“传说，一个把 Rust 编译器描述成一个妖怪的故事：以我的经验来看，它主要发生在初学者和 1% 试图微优化代码,或突破边界的人身上。大多数有经验的 Rust 开发人员都知道如何精确地对代码进行建模，这样就不会浪费时间在设计问题上与编译器进行斗争，并且可以一眼就发现反模式，就像大多数人知道如何在正确的道路一侧，驾驶汽车以避免事故一样，同时注意到那些做得不对的人！
