>From the PEP -3106.
"This PEP proposes to change the .keys(), .values() and .items() methods of
the built-in dict type to return a set-like or unordered container object
whose contents are derived from the underlying dictionary rather than a
list which is a copy of the keys, etc.; and to remove the .iterkeys(),
.itervalues() and .iteritems() methods."
