This issue was originally filed by edouardta...@gmail.com

What steps will reproduce the problem?

Following code:

class MyClass {
  static void A() {}
  static void B() {}
}

void main() {
  MyClass..A()..B();
}

What is the expected output? What do you see instead?

Expected output would be that MyClass.A() is called and then MyClass.B().

Instead I get this (in Dartium):

Exception: Class '_Type' has no instance method 'A'. 

NoSuchMethodError : method not found: 'A' 
Receiver: Type: class 'MyClass' 
Arguments: []

What version of the product are you using? On what operating system?

Dart SDK version 0.4.1.0_r19425
Ubuntu 12.04 64-bit

Please provide any additional information below.

The IDE accepts the code as valid.

My understanding is that the VM has the correct behaviour, but I want to check with Gilad first.

THe VM is behaving as specified. MyClass is an expression in this context, and as such represents an object of type Type.

Changing the language to allow this sort of thing is in many ways desirable, but has implications that need to be thought through. That is why it isn't this way at this point. It may change in the future.

Removed Type-Defect, Area-VM labels.
Added Type-Enhancement, Area-Language, Accepted labels.
