Dartc allows a method and getter/setter with the same name

When getter or setter(implicit or explicit) and a method with the same name are divided into different classes(interfaces), dartc does not produce a compile-time error.
Dartc(r2810) executes this code without errors:
Test 1:
class A {
  foo(){throw new A();}
}

class C extends A {
  get foo() { return "foo()"; }
}

main() {
  new C().foo();
}

Test 2:
class A {
  var foo;
}

class C extends A {
  foo() { return "foo()"; }
}

main() {
  new C().foo();
}

Test 3:
class A {
  void set foo(var x){}
}

class C extends A {
  foo(value) {}
}

main() {
  new C().foo(1);
}

Test 4:
interface S {
  void m();
}

interface I extends S {
  int m;
}

class A implements I {}

main() {
  new A();
}

Test 5:
interface S {
  int m;
}

interface J extends S {
  int m();
}

class A implements J {}

main() {
  new A();
}

in my tests on r2899, these are all correctly producing compile-time errors with dartc.

co19 test failure is not fixed: tests/co19/src/Language/07_Classes/2_Getters_A04_t03.dart

class A {
  var foo;
}

class C extends A {
  foo() { return "foo()"; }
}

Section 7.2 Getters says that this could be a compile-time error but it is only a warning.
