And which he seemed to think didn't work for some
reason, but it seems fine as far as I can tell:

Python 2.7 (r27:82500, Oct 15 2010, 21:14:33)

 >>> gv = dict.itervalues
 >>> d = {1:'a', 2:'b'}
 >>> gv(d)
<dictionary-valueiterator object at 0x2aa210>

% python3.1

 >>> gv = dict.values
 >>> d = {1:'a', 2:'b'}
 >>> gv(d)
dict_values(['a', 'b'])
