It depends. If you are just using ufuncs inside, you don't have to do
anything. Your function will work just fine with arrays and scalars.
If you're doing something else, like looking at .shape or using .sum()
or something, then you might need to actually do something. Exactly
what depends on the details, though. Can you provide more details
about what your function does?
