efficient memoize decorator?

[thattommyhallll@gmail.com]

does not seem to work for standalone functions, this is a method
decorator only then?

Traceback (most recent call last):
  File "prob14memoize.py", line 94, in ?
    length = col(i,1)
  File "prob14memoize.py", line 49, in __call__
    object = self.cache[args] = self.fn(self.instance, *args)
AttributeError: 'Memoize' object has no attribute 'instance'

cheers, tom
