Hello, When creating a Matrix from another one, no new object is created
m1 = Matrix(2, 2, range(4)) m2 = Matrix(m1) m1 is m2 returns True, so changing m1 will also change m2. I know I can use m1.clone(), but since SomeClass() usually creates a new object, this took me rather by surprise. Is this intended behavior?
