+- New module: sets, defines the class Set that implements a mutable
+ set type using the keys of a dict to represent the set. There's
+ also a class ImmutableSet which is useful when you need sets of sets
+ or when you need to use sets as dict keys, and a class BaseSet which
+ is the base class of the two. (This is not documented yet, but
+ help(sets) gives a wealth of information.)
