Ugh.  Syntactic sugar like that leads to language obesity.  Anyway, you can 
already do what you want with just a little bit of work.  Define a class 
(perhaps a subclass of dict, if you like) with a __getattr__ method.  Then 
you can just do

foo.bar.baz.x = y

with no changes needed to the language.
