[swift-evolution] [Review] SE-0022: Referencing the Objective-C selector of a method

We discussed this proposal during our core team review meeting, and concerns were raised about the implementability of the proposed 'Selector(Type.method)' syntax. Producing the selector is something that can't quite be modeled as a real initializer, so the type checker would have to perform heroics to disambiguate a selector literal reference from a proper initializer call. We recommend reconsidering alternative syntactic forms for referencing the selector. Potential options include:
- A unique prefix identifier, such as `objc_selector(Type.method)`, as you had originally proposed, or
- Taking advantage of the fact that functions don't have members to ascribe special behavior to 'Type.method.objcSelector', or something like it.

> The goal of the review process is to improve the proposal under review through constructive criticism and, eventually, determine the direction of Swift. When writing your review, here are some questions you might want to answer in your review:
> • What is your evaluation of the proposal?
> • Is the problem being addressed significant enough to warrant a change to Swift?
> • Does this proposal fit well with the feel and direction of Swift?
> • If you have you used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
> • How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
