[issue8134] collections.defaultdict gives KeyError with format()

Oops, thanks.  I should have known that.  However, should this work?  This is what initially led me to file this ticket.  My initial example was a bad one.

>>> from collections import defaultdict
>>> d = defaultdict(int)
>>> d['bar'] += 1
>>> "{bar}".format(**d)
'1'
>>> "{foo}".format(**d)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'foo'
