struct Fug
{
    bool opEquals(ref const Fug y) const {
        return false;
    }
}

struct Fig
{  // line 29
   Fug f;   
   bool opEquals(Tdummy=void)(ref const Fig y) const {
      return false;
   }

   bool opEquals(T: int)(T y) const {
      return false;
   }
}

void main() {
  Fig fx, fy;
  if (fx==2) {}
}
---
And the error message is nonsense:

bug.d(29): Error: function bug.Fig.opEquals conflicts with template
bug.Fig.opEq
uals(Tdummy = void) at bug.d(31)

Worked in 2.036.
--------
// Workaround is to change Fug opEquals to:
    bool opEquals(Tdummy=void)(ref const Fug y) const
