May be tuple unpacking can be extended to support:
(a,b,c,*args,d,**kwds) = p,q,*a1,r,s,**k1
where "p,q,*a,r,s" is equivalent to itertools.chain((p,q),a,(r,s)) 
(something like scheme's ",@")

And in parallel, function argument unpacking could be extended to support
def func(a,b,c,*args,d,**kwds): pass

But I guess this would not fly:
1. I am not sure about how default values in function arguments would be 
2. PEP 3113 disallows tuple unpacking as part of function arguments
3. Currently, *args is populated with a list (and not tuple) in tuple 
and possibly a dozen other issues.
