You could do something like this:
class wrapper:
def __init__(self, object):
self.wrapped = object
def __getattr__(self, attrname):
print '** get attribute: ', self.wrapped, attrname
return wrapper(getattr(self.wrapped, attrname))
def __call__(self, *args, **kwargs):
print '** call with args: ', self.wrapped, args, kwargs
return wrapper(self.wrapped(*args, **kwargs))
x = wrapper([1,2,3])
x.append(4)
I haven't thought about it too much though.
