The "@compile-error" comment is an old not-great way of defining static error tests. Note that the behavior of the code under test here had changed significantly, but the test didn't catch it at all because "@compile-error" is too coarse-grained. See: https://github.com/dart-lang/sdk/issues/45634 Change-Id: I4b6c4e1fd36770e13f7b5ca100b42b0b8b2983ae Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/296121 Commit-Queue: Jake Macdonald <jakemac@google.com> Reviewed-by: Jake Macdonald <jakemac@google.com> Auto-Submit: Bob Nystrom <rnystrom@google.com>
