Notice: this was never a multi-test. It says //, not ///.

Any idea why anyone would have thought this to be a compile-time error?

I think there may have been some confusion about what the implied interface of a
class should be. When Gilad arrived he put his foot down and made sure it was
done right.

-    Expect.equals(0, c2.foo); // 02: compile-time error
+  try {
+    c1.foo;
+    Expect.fail('expected a NoSuchMethodException');
+  } catch (NoSuchMethodException ex) {
+    // Expected error.
+  }
+  try {
+    c2.foo;
+    Expect.fail('expected a NoSuchMethodException');
+  } catch (NoSuchMethodException ex) {
+    // Expected error.
   }
   Expect.equals(true, c1 is BaseClass);
   Expect.equals(true, c1 is !ExtendsClass);
   Expect.equals(true, c2 is BaseClass);
   Expect.equals(true, c2 is ExtendsClass);
   Expect.equals(true, c2 is !ImplementsClass);
   Expect.equals("BaseClass", "${new BaseClass()}");
 
   // Verify we don't inherit toString from BaseClass
-  Expect.equals("${new Object()}", "${c1}");
-  Expect.equals("${new Object()}", "${c2}");
+  Expect.notEquals("BaseClass", "${c1}");
+  Expect.notEquals("BaseClass", "${c2}");
 }
