[PEP 203] Augmented Assignment

[David Goodger]

Here's some food for thought:

Perhaps the cleanest way to implement augmented assignment, syntactically,
would be to add an optional boolean argument to the __add__() etc. hook
functions, resulting in signatures like

    def __add__(self, other, augmented):

This could be implemented in a backwards-compatible way as follows: the
interpreter checks for a hook function with the right signature, uses it if
present, then checks for the old-style hook as before. Is this feasible?

Has this approach ever been raised? (I've only been lurking on the
Python-Dev list for a few weeks now. :>)
