I am using is in one of my recent projects. I was thinking of
it sort of like "static" variables in C.
I use a decorator to create the variables ...
def static(**kw):
'''
Used to create a decorator function that will add an
attribute to a function and initialize it.
>>> @static(foo=5)
... def bar():
... print bar.foo
... bar.foo += 1
...
>>> bar()
5
>>> bar()
6
'''
def decorator(f):
f.__dict__.update(kw)
return f
return decorator
