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?
