It looks that A is defined twice.

Other errors in augmented_expression_A01_t09_lib.dart are because the analyzer does not do implicit call() invocation yet.

unexpected analysis errors in augmented_expression_A01_t09.dart:
- Line 51, column 7: COMPILE_TIME_ERROR.DUPLICATE_DEFINITION
  The name 'A' is already defined.

- Line 70, column 32: COMPILE_TIME_ERROR.NOT_ENOUGH_POSITIONAL_ARGUMENTS
  1 positional argument expected by 'A.new', but 0 found.

unexpected analysis errors in augmented_expression_A01_t09_lib.dart:
- Line 22, column 43: COMPILE_TIME_ERROR.INVOCATION_OF_NON_FUNCTION_EXPRESSION
  The expression doesn't evaluate to a function, so it can't be invoked.

Ah, actually there are other type issues in the augmentation.

augment class C {
  augment static String get staticGetter {
    Expect.equals("A(C.staticGetter).call", augmented());
    var f = () {
      return augmented();
    };
    Expect.equals("A(C.staticGetter).call", f());
    return A("Augmented");
  }

Note that we return A from String get staticGetter.
