+// 7.1 Instance Methods:
+
+// "Instance methods are functions (6) whose declarations are

+
+// 7.6 Static Methods
+
+// "Static methods are functions whose declarations are immediately
+// contained within a class declaration and that are declared

+// declared by C."
+
+// 7.7 Static Variables
+
+// "Static variables are variables whose declarations are immediately
+// contained within a class declaration and that are declared
+// static. The static variables of a class C are those static
+// variables declared by C."
+
+// "A static variable declaration of one of the forms static T v;,
+// static T v = e; , static const T v = e; or static final T v = e;
+// always induces an implicit static getter function (7.2) with

So you can have a static method called i and a static variable called i in the
same class? That seems wrong.

[ahe, 2012/06/20 09:04:40]

No. Static members are not inherited.
It is wrong :-)

[zundel, 2012/06/20 09:08:57]

Its the lesser of evils maybe.  Unqualified accesses might behave even more
mysteriously than they already do.

[ahe, 2012/06/20 11:00:18]

Actually, after removing the "compile-time error" tags, there are two
declarations of i in the same class (line 62 and line 71). That is not correct.

I have fixed the bug and exposed a bug in dart2js :-(

 
-  static var instanceMethod; /// 05: compile-time error
+  // According to 7.1, instance methods include those of the
+  // superclass, and according to 7, it is a compile-time to have an
+  // instance method and static method with the same
+  // name. Furthermore, according to 7.7 a static variable induces an
+  // implicit getter function (a static method).
+  static var instanceMethod2; /// 05: compile-time error
 
-  foo() {}
+  foo() => 'foo';
 }
 
 main() {
-  new Sub().foo();
+  Expect.equals('foo', new Sub().foo());
+  Expect.equals('top level', m());
+  Expect.equals('super', Super.m());
+  Expect.equals('sub', Sub.m());
+  Expect.equals('super', Super.i);
+  Expect.equals('sub', Sub.i());
+  Expect.equals('super', new Super().instanceMethod());
+  Expect.equals('sub', new Sub().instanceMethod());
