I don't think the augmented assignment patch is ready to be checked in,
though !

There are a number of crude hacks that might be solved better: the
2-argument opcodes, for instance, could posisbly be avoided by abusing the
proposed 'extended_arg' opcode. And the patch re-uses the binary opcodes as
augmented-assignment opcodes, merely because those #defines were already
available in both ceval.c and compile.c: this would 'break' if we wanted to
incorporate a new operator in augmented-assignment without adding a new
'normal' opcode for that operator.

I'm still working on the PEP, really :) It's just a pretty long one, trying
to explain all the intricate details and the simple elegance of the solution
<wink>. Perhaps it'll inspire some discussion in the details of the patch,

Humb-ly y'rs,
