Imagine that we have a more generic case where instead of d.keys()
and d.clear() there are statements which may throw. Then the above
is equivalent to:

      def f(d):
          try:
              result = d.keys()
          except:
              d.clear()
              raise
          else:
              d.clear()
              return result
