Start: ./language[_strong]/closure_side_effect_test.dart End: ./language[_strong]/compile_time_constant2_test.dart Except for tests/language_2/closure_type_test.dart, all other files has been copied automatically by the tool. R=jcollins@google.com, whesse@google.com PS: Forgot to run git cl upload command right after the migrate_tool, which I should have done, to make the automatic and manual changes clearer.
