I had some off-list contact with Rudi and generally have agreed with
these changes.
However, there may be some value in following Python's lead. In Python
2 they had a `__cmp__` magic method and in Python 3 they removed it
and added all of these:
__lt__
__le__
__eq__
__ne__
__gt__
__ge__
This permits things such as NumPy to overload < to do an element-wise
comparison of the members; something like this:
np.array([1, 3, 5, 7]) < np.array([2, 1, 6, 6])
// evaluates to np.array([true, false, true, false)
If we pursue this Pythonic route then we would also need methods for +
- * / % etc. I do not want to derail the conversation too much, but it
does seem opportune to discuss operator overloading more generally.
