I i need a decorator that adds a local variable in the function it
decorates, probably related with nested scopes, for example:
def dec(func):
def wrapper(obj = None):
if not obj : obj = Obj()
<bind obj to func>
return func()
return wrapper()
@dec()
def fun(b):
obj.desc = 'marked'
obj.b = b
return obj
so the call to fun : fun(obj = myobj,'b argument')
or fun('b argument')
So the function "fun" assumes it has an obj instance and other instance
objects computed by the decorator, this decorator will be like a generic
factory for this kind of functions,which depends on the decorator to work.
