Tested it on Windows 7, using dmd 2.066.1: works for me. The exact code I tested (just commented those "..." out): ---- struct Vector3 { public double[3] _p; //... Vector3 opBinary(string op)(in Vector3 rhs) const if (op == "+"){ Vector3 result; result._p[] = this._p[] + rhs._p[]; return result; } //... } unittest{ auto a = Vector3([2.0, 2.0, 0.0]); auto b = Vector3([1.0, 2.0, 1.0]); Vector3[] c = [a]; Vector3[] d = [b]; Vector3 e = a + b; Vector3[] f; f[] = c[] + d[]; } ---- And the command line: dmd -main -unittest test.d
