Summary: Let assign to as raise SyntaxWarning as well

Initial Comment:
according to the Python Language Reference Manual:
> In some future version of Python, the identifiers
> as and None will both become keywords.

Hence, it seems natural to me to raise a SyntaxWarning
when assigning to
either of these. However, the current Python
implementation doesn't:

103 >>> None="foo"
<stdin>:1: SyntaxWarning: assignment to None
104 >>> as="foo"
105 >>>

For consistency and cleanliness, assignment to 'as'
should raise a SyntaxWarning as well. Currently, it's
possible to not know it'll be a keyword and use it as a
variable; people shouldn't, so a SyntaxWarning would be
good.

This may be too late if as becomes a keyword in the new
with/do/whatever-statement...

I'm not sure whether this should be considered as a feature.
I'd call it a minor wart... I'm also not sure about the
category, is this 'Python interpreter core' or am I right
with 'parser/compiler'?
