A hashability problem

Using Swift
26

So this is not acceptable?

let mainStageTonight: Set<ComparableMusicPerformer> = [
  .init(FreddieMerqurie()),
  .init(JimmyHendrix()),
]

struct ComparableMusicPerformer: Hashable, Comparable {
  private var storage: MusicPerformer

  statuc func ==(lhs: Self, rhs: Self) -> Bool { ... }
  ...
}
