The entirety of opEquals:

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;
}
}
```
