thanks for the tip. actually, the essence of what i wanted to 
ask was: "can that SOMETHING be a list of more than one elements 
which will be _flatly_ added to the result list." as another 
example, can i generate this list

  [1,1  2,2,2,  3,3,3,3, 4,4]

with a list comprehension that contains one 'for' clause?
