Well, you could easily simulate that with proxy object,
class SymbolicReference(object):
def __init__(self, ns, name):
self.__ns = ns
self.__name = name
def __get(self):
return self.__ns[self.__name]
def __getattribute__(self, attr):
try:
return object.__getattribute__(self, attr)
except:
return self.__get().__getattribute__(attr)
def __repr__(self):
return self.__get().__repr__()
def __str__(self):
return self.__get().__str__()
>>> a = 1
>>> b = SymbolicReference(globals(), 'a')
>>> b
1
>>> a = 10
>>> b
10
