Using Lists as facts is not a good practice. It is always convenient to use a wrapper class. But if you want to go with the List you could write something like this:

Rule "List_iterate"
when
  $list : List()   //Be careful, this will match against all the Lists you have in your session.
  $str : String() from $list
then 
  // some action of $str
end

Hope it helps.
