Summary: Poor error message for augmented assign

Initial Comment:
>>> [1,2] += [2,3]
SyntaxError: augmented assign to list not possible

A similar error message is generated when augmented 
assignment is used on tuple literals.

This error message is desceptive because augmented 
assignment is allowed on both of those types. 

I would change the message to:

SyntaxError: can't assign to literal

I may generate a patch for this, but not anytime soon.

Jeremy, do you agree?  How about adding the word literal to
the error msg, so it reads:

 * augmented assign to literal list not possible
