Compilation fails with:
breaker.d(11): Error: identifier 'r' is not defined
breaker.d(7): Error: template instance breaker.ElemType!() error instantiating

given the following for breaker.d:

module breaker;
import breaker;

void main(){}

struct Test {
  static if (is(ElemType!())) {}
}

template ElemType() {
  alias r ElemType;
}




Note that when you remove "import breaker;", the code compiles without error. 
This was distilled from a 4 module circular import.
