Unfortunately, abstract interpretation with widening is not monotone. Hence the (recursive) abstract interpretation of a loop body that again contains a loop may result in a non-monotone -function. Therefore our narrowing interation needs to check at every step +function. Therefore our narrowing iteration needs to check at every step that a post-fixed point is maintained, and we cannot prove that the precision increases. *}
