The whole point was to have a function (or class) that accumulates a
sequence and counts it. collections.defaultdict(lambda: 0) doesn't
achieve this on its own because it only knows how to handle sequences of
(key, value):

The feature request here was mainly a request to provide an abbreviation
of a very common 4-line function.
