** Presubmit ERRORS **
File output does not match dartfmt.
Fix these issues with:
/usr/local/google/home/regis/dart2/sdk/tools/sdks/linux/dart-sdk/bin/dartfmt -w
/usr/local/google/home/regis/dart2/sdk/tests/language/regress_29243_test.dart

Presubmit checks took 6.0s to calculate.

Was the presubmit check useful? If not, run "git cl presubmit -v"
to figure out which PRESUBMIT.py was run, then run git blame
on the file to figure out who to ask for help.

I'd for sure love to see what regress_29243_test.dart looks like.

You can see the line in the bug report, but here is the full test:

import "package:expect/expect.dart";
int Function() x = () => 42;
int Function(int Function()) y = (int Function() x) => x();
List<int Function()> l = <int Function()>[()=>42, x];
main() {
  Expect.equals(42, y(l[1]));
}

I was finally able to upload the test git cl upload --bypass-hooks
