For example, in cases like this:

  def foobar(ary)
    # we need to "declare" a variable here under the current behavior,
    # but no longer under the new behavior
    ary.each do |elem|
       if some_condition_on_elem(elem)
          found = elem     # "found" will be available during whole #foobar.
          break
       end
    end
    some_work_with_found_elem(found)
    return found
  end
