If optimizations are less important, then don't use __slots__, i

I kind of liked the ability to partially use iterato

rubbish. using a single constructor that handles two common use cases is
perfectly Pythonic (especially if you're targeting casual programmers).

I am writting a Vector3D class as a teaching aid (not for me, for
others), and I find myself pondering over the __init__ function. I want
it to be as easy to use as possible (speed is a secondary

Heres the __init__ function I have at the moment.
class Vector3D(object):
__slot
