When I change the class Wrapper to following, the class Foo works:
class Wrapper(object):
def __init__(self,x):
self.func_name = x.func_name
self.x = weakref.ref(x.im_self)
def __call__(self,*args,**kwargs):
x = self.x()
if x is None:
print "lost reference"
else:
return getattr(x,self.func_name)(*args,**kwargs)
But that's ugly. Any better idea?
