These tools confirm it plays nice with Python: dart tool/generate-testcases-dart/main.dart | python tool/validate-testcases-python/main.py python tool/generate-testcases-python/main.py | dart tool/validate-testcases-dart/main.dart

These tools confirm it's self consistent: dart tool/generate-testcases-dart/main.dart | dart tool/validate-testcases-dart/main.dart
