+0 I think this is with worth considering.  Whenever the use case arises, the 
workaround is awkward.  Code would be clearer if assignment expressions were 
liberalized to allow unpacking.

The PEP aspired to avoid complex lvalues that might be hard to read or that had 
tricky semantics.  Unpacking is one the simpler cases and would be mostly 
harmless and sometimes beneficial (and not just for the uncommon case of 
wanting simultaneous assignment).
