Subclassed dict as globals

In Python 2.4 the following works:
>>> class G(dict):
... def __getitem__(self, k):
... return 'K' + k
>>> g = G()
>>> exec 'print x, y, z' in g
Kx Ky Kz
...while in Python 2.3 it fails with NameError: name 'x' is not defined.
Is this an "accidental feature", or can I count on this working in
future versions of Python? For that matter, is there a way to do this
(intercept global variable accesses) in Python 2.3?
