What steps will reproduce the problem?
Run the following test:
class C {
  C() {}
  final _val;
}

main() {
  C c = new C();
}

What is the expected output? What do you see instead?
Expected: compile-time error
Actual: test compiles without errors.

What version of the product are you using? On what operating system?
dartc r2810, Ubuntu 10.04

Please provide any additional information below.
The same applies to the top-level final variables:
final foo;//should be an error

main() {
  Expect.isTrue(foo is List);
}

It should be noted that duplicating initializes also failed to report errors.
