Not sure about this. Why do you pass name and info to the superclass? I
thought these attributes were stored in the subclass. If not, why the two
following lines?
>         self.name = name
>         self.info = info

Well, basically I have a dictionary of lists containing unnamed callable
functions to which I wish to add some further info such as an readable name,
description, authour, etc. So help me here...

Using composition I'd have
> class funct(call_me):
>     def __init__(self, func, name='', info = []): # description, authour,
etc
>         self.func = func
>         self.name = name
>         self.info = info
using
a_call_me = call_me(print_message)
my_func = funct(a_call_me, 'fred', [])

Using inheritance I'd have
> class funct(call_me):
>     def __init__(self, func, *args, **kw, name='', info = []): #
description, authour, etc
>         super(call_me, self).__init__(func,*args, **kw)
>         self.name = name
>         self.info = info
using
my_func = funct(print_message, None, None, 'Fred', [])

Is this right or am I *horribly* wrong?! Thanks for the help. matthew.
