You could look at something like the following to turn the class

can optionally be written as:

Thanks folks. Will write my own class Andrew
PS So for the record, this works and isn't as ugly/verbose as I was
expecting:
class TaggedWrapper():
def __init__(self, generator, logMixin, stream):
self.__generator = generator
self.__tag = '%...@%s' % (logMixin.describe()

You'll see the same behavior if you attempt to add an attribute to an
instance of object as well.
>>> object().t = 5

Hi,
(I searched back and found some previous discussion on generator

I want to associate some data with a generator. This is in a
decorator function, as it happens;
