Description William Moore 2010-08-20 14:10:04 UTC 
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.

could be a variation of bug 4302.
Comment 2 William Moore 2010-10-05 07:45:47 UTC 
This seems to be fixed in the latest DMD 1.064.
