Yes.  These are and should be legal

del a, b[1], c.d
del (e+f).g[9]().h

but I think this should not be legal

del a, (b, c)

That should raise

   SyntaxError: can't delete tuple

and I would also like it if the following raised the same error

   del (a, b)

but people use it now and I can see that perhaps, like with the from  
statement, using '()' for long expressions is useful

   del (some_very_large_variable_name[1],
        another_large_variable_name[2].with_attribute)


I also think

   del a,

should not be legal ("SyntaxError: trailing comma not allowed without  
surrounding parentheses"?), but that's getting into my own personal  
preferences.
