A free-standing opEquals won't work. It needs to be a method of 
the class. So:

```d
class Matrix(size_t X, size_t Y = X)
{
     /* ... */

     bool opEquals(const Matrix m2)
     {
         for (int i = 0; i < this.data.length; ++i)
             if (this.data[i] != m2.data[i]) return false;
         return true;
     }
}
```
