Here is the reduced testcase. Error disappears if I move definition of Foo
(line 16) anywhere before definition of Bar (line 13).

struct Arr(T) {                 // 1
  T[] dArr;                     // 2
  alias dArr this;              // 3
  bool opEquals(Arr!T d) {      // 4
    foreach(idx, it; d) {       // 5
      if(this[idx] != it) {     // 6
        return false;           // 7
      }                         // 8
    }                           // 9
    return true;                // 10
  }                             // 11
}                               // 12
class Bar {                     // 13
  Arr!Foo fooQ;                 // 14
}                               // 15
class Foo {}                    // 16
void main() {}                  // 17
