relates to:

  • SR-5392 Inconsistent "invalid redeclaration of typealias"
  • SR-5440 Typealias in constrained extension misinterprets the where clause

Issue Description:

struct Base<Element: Equatable> {
  struct Glue {
  }
}

protocol Unifiable {
  associatedtype Glue
}

extension Unifiable where Self: Equatable {
  typealias Glue = Base<Self>.Glue
}
