In the chat, Anders had a problem with forward references.
I believe this code should work. Is this error really solved?
I attached the sources.

the bug is fixed in 1.0. i don't know if that's a good news or a bad one. maybe it would hide something? would it fail at more complicated cases?

------- Comment #10 from braddr@puremagic.com  2007-01-23 00:58 -------
Taking a closer look at the attachment, compiling dbug/bug/queue.d via 'dmd -c queue.d' produced an error:

$ dmd -c queue.d
queue.d(9): class queue.MessageQueue is forward referenced when looking for
'ListHead'
queue.d(9): class queue.MessageQueue is forward referenced when looking for
'ListHead'
arm.d(12): Error: no property 'ListHead' for type 'queue.MessageQueue'
arm.d(12): Error: MessageQueue.ListHead is used as a type
arm.d(12): variable arm.Arm.mqueue voids have no value

Compiling the entire set together: dmd main.d list.d queue.d arm.d (or in any other order that I tried) succeeds.  This indicates to me that the bug is NOT fixed.  The code is certainly more verbose than it needs to be to be a minimal test case, but it _does_ show that there's an error still.  Re-opening the issue.

yep , i tested it on 1.005. it still fails. umm dmd -c queue.d would have the forward reference problem.

A simpler example:

=== test.d ===
import list, arm;

class Queue {
  mixin List;
  Arm a;
}

class MessageQueue : Queue { }

=== arm.d ===
import list, test;

class Arm {
  mixin List;
  MessageQueue.ListHead mqueue;
}

=== list.d ===
template List() {
  struct ListHead { }
}

===================
compile with:
 dmd test
gives:
test.d(8): Error: class test.MessageQueue is forward referenced when looking
for 'ListHead'

Even simpler:

=== test.d ===
import test;

class Arm {
  typedef int ListHead;
  MessageQueue.ListHead mqueue;
}

=== arm.d ===
import arm;

class Queue {
  typedef int ListHead;
  Arm a;
}

class MessageQueue : Queue {
}
