+# XXX Until generators are part of the language, examples in doctest'ed
+#     modules will inherit doctest's __future__ settings (see PEP 236 for
+#     more on that).  In the absence of a better working idea, the std
+#     test suite needs generators, while the set of doctest'ed modules that
+#     don't use "yield" in a generator context may well be empty.  So
+#     enable generators here.  This can go away when generators are no
+#     longer optional.
