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

[David Hart]

What effect would that have? Would the options still return a type (Selector) that is CustomStringConvertible or would it just be compiler magic?

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:
