While this prevents\nsome clever tricks, it permits catching (at runtime or statically\nvia vet) type errors equivalent to the ones that can be detected\nby type assertions.\n\n  if e :\u003d os.PathError{}; errors.As(err, \u0026e) {  // error, os.PathError does not implement error\n  if e :\u003d \u0026os.PathError{}; errors.As(err, e) {  // error, os.PathError does not implement error\n  if e :\u003d \u0026os.PathError{}; errors.As(err, \u0026e) { // ok\n\n  var e interface{ Timeout() bool }\n  if errors.As(\u0026e) \u0026\u0026 e.Timeout() { // ok\n\nChange-Id: I3607ac62fbe8aebef3c1aeec3fb414fb41afcdda\nReviewed-on: https://go-review.googlesource.com/c/161899\nReviewed-by: Jonathan Amsterdam \u003cjba@google.com\u003e\n",
