Question on decorators in general. Can you parameterize those?

If you want to call prepostdecorator with 2 arguments, you need to write
it this way. A few options:
Sorry, I forgot my favorite one:
(4) Use a class and functional.partial:
py> class prepostdecorator(object):
... def __init__(self, pre, post, function):
... self.pre, self.post, self.function = pre, post, function
... def __call__(self, *args, **kwargs):
... self.pre()
... result = self.function(*args,**kwargs)
... self.post()
... return result
...
py> @partial(prepostdecorator, dopre, dopost)
... def sayhello(name):
... print "Hey %s, nice to meet you" % name
...
py> sayhello('Tom')
call pre
Hey Tom, nice to meet you
call post
Woo-hoo, I got rid of all the nested functions! ;)
