is duplicated by:

  • SR-14091 Improve "ambiguous without more context" error on misusing SwiftUI's Axis

Issue Description:

import SwiftUI

struct S {}

struct V: View {
  var s: [S]
  var body: some View {
    let x = PinnedScrollableViews(s)
    Spacer()
  }
}

This fails to produce a diagnostic on recent main @ 47a4ad2, as well as with Swift 5.3.2.
