Or to link this to PEP 3150:

    given:
          mem = collections.Counter()
    def do_and_remember(val, verbose=False):
          result = do_something(val)
          mem[val] += 1
          if verbose:
              print('Done {} times for {!r}'.format(_mem[val], val))

(Or the other way around)
