Why does Py5Vector have a .copy property instead of a .copy() method?

[villares]

Is it for performance?

I know Py5Vector implementation uses NumPy arrays inside, and an np.array object also has a .copy() mehod... as old PVector objects did.

Just curious...

I did that to simplify the coding when you need to do something with a copy. For example, if v1 = PyVector(1, 2, 3), then you can access v1.copy.rotate(py5.PI / 2, dim=1) without rotating v1. I guess it wouldn't have been too much trouble if you needed to also include the () but this makes the code a bit easier to type and is similar to norm, which works the same way.
