If I understand you right, what you want is something like::
class MyDict(object):
def __getitem__(self, key):
...
def __setitem__(self, key, value):
...
... magic incantation to use a MyDict instance for class Foo ...
class Foo(object):
a = 1 # calls MyDict.__setitem__('a', 1)
def bar(self): # calls MyDict.__setitem__('bar', <func>)
...
b = a + 2 # calls MyDict.__getitem__('a') and then
# calls MyDict.__setitem__('b', 3)
If that's right, then the answer is "no, you can't do this". There was
some discussion of allowing such a thing in Python 3.0, but it fizzled.
(Check the python-3000 archives if you're interested.)
So what's the real problem you're trying to solve?
