Augmented assignment is not supported in expression form::

     >>> x +:= 1
       File "<stdin>", line 1
         x +:= 1
             ^
     SyntaxError: invalid syntax

I would have expected :+=, but agree with the omission.

x = x op 1 is abbreviated to x op= 1, so x := x op 1 would be 
abbreviated to x op:= 1. That's what's used in the Icon language.
