Yes, but the whole point was to be more concise (specifically, better  
than setting the elements one by one, but even this is somewhat  
redundant). The reason I did it the way I did was because

cdef foo = x

gets translated to

cdef foo
foo = x

and so disallowing assignments in one place, but not in another, and  
allowing assignments to array types just once, etc. was a whole lot  
more complicated that what I wanted to deal with at the time.  
Eventually we will get there.
