PEP 3104 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 [24].)
"""
The PEP metadata says it was approved and implemented in 3.0, yet this
part never seems to have been implemented:
Python 3.7.0a3+ (heads/master:53f9135667, Dec 29 2017, 19:08:19)
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def f():
... x = 1
... def g():
... nonlocal x = 2
File "<stdin>", line 4
nonlocal x = 2
^
SyntaxError: invalid syntax
Was this just an oversight, or did it get rejected at some point and
no-one remembered to update that PEP?
