It's consistant, not a wart from my perspective. If an object is
modified, it is not returned.
For every part of the (admittedly small) python library I know, that
is the case. Returning None is a hint that the object is modified.
So then the question becomes, why don't append(), sort(), reverse()
return a new list and not modify the original? Are mutable objects
themselves a wart on the langauge?
