My advice would be to stick with the function call. It's consistent with
most other array operations (esp. when you consider that the vast majority
of operations on arrays are functions defined in third party libraries like
yours), and the more things we add to the core array object, the more work
it is for people implementing new array-style containers. I definitely
would not recommend subclassing ndarray for this purpose -- there are all
kinds of subtle problems that you'll run into that mean it's extremely
difficult to do well, and may well be impossible to do perfectly.
