I missed that, so for future reference, the PEP says:

"""
A shorthand form is also permitted, in which nonlocal is prepended to
an assignment or augmented assignment:

nonlocal x = 3
The above has exactly the same meaning as nonlocal x; x = 3. (Guido
supports a similar form of the global statement.)
"""

and refers to Guido's post at

http://mail.python.org/pipermail/python-3000/2006-November/004166.html

In any case, the relevant issue is

http://bugs.python.org/issue4199

and it should probably be marked as "after moratorium".  Meanwhile an
implementation status note can be added to the PEP to avoid this issue
being brought up again.
