Thanks for the clarification, one detail about the order between 
incrementing and setting $$lastIteration_i:

{
    let i = $$lastIteration_i;   //create and initialize per iteration i
    if (!(i<10)) break;
   {
       let i;
    }
*    i++;
    $$lastIteration_i = i;*
}

Should it be*
$$lastIteration_i = i;
i++;

*instead, given what the spec says?
