How about not relying on noSuchMethod here and switch this to an Expect?

[hausner, 2013/06/05 18:37:54]

Done. We now rely on another unhandled exception type :)

Unhandled exception:
Expect.equals(at index 13: Expected <...from main script>, Found: <...from
library>) fails.
#0      Expect._fail (package:expect/expect.dart:368:5)
#1      Expect.equals (package:expect/expect.dart:99:14)
#2      main (file:///src/d1/dart/tests/language/extends_test.dart:20:16)
