Me too. I'm against iteritems and friends coming back.
I've been burned in the past with the burden of writing a mapping class with
the many methods such a thing must support; both items() and iteritems() and

As far as I know, all you have to implement yourself, to support the
dict-like interface, are:
- __getitem__
- __setitem__
- __delitem__
- __iter__
- __len__
MutableMapping can implement the rest. This wouldn't change with the
re-addition of the iter* methods.
You really have to use MutableMapping now that keys/items/values are
complicated objects: it's much harder to implement dict-like objects
from scratch in 3.x than 2.x.
Fair point.
Thank you,
