许多读者来信询问关于Selective的相关问题。针对大家最为关心的几个焦点，本文特邀专家进行权威解读。
问：关于Selective的核心要素，专家怎么看？ 答：A few of the iFixit team just spent a week at Barcelona’s Mobile World Congress, helping Lenovo to demonstrate its new 10/10 laptops. One the last day of the show, students can attend for free, and they were super-interested in such a repairable machine. These folks are young enough that they have never seen what used to be the industry norm: modular laptops that could be completely repaired with nothing but a screwdriver. I got to wondering how they’d react to seeing some of Apple’s neat battery-removal schemes over the years.

问：当前Selective面临的主要挑战是什么？ 答：In iBooks and early MacBooks the battery formed a part of the case. You’d unlock it by turning a slot with a coin, and then angle the battery off. That was it.

问：Selective未来的发展方向如何？ 答：The idea of passing implementations automatically is also known as implicit parameters in other languages, such as Scala and Haskell. In Rust, however, a similar concept is being proposed, known as context and capabilities, which is what we will explore next.
问：普通人应该如何看待Selective的变化？ 答：In this talk, I will explain how coherence works and why its restrictions are necessary in Rust. I will then demonstrate how to workaround coherence by using an explicit generic parameter for the usual Self type in a provider trait. We will then walk through how to leverage coherence and blanket implementations to restore the original experience of using Rust traits through a consumer trait. Finally, we will take a brief tour of context-generic programming, which builds on this foundation to introduce new design patterns for writing highly modular components.
