Subject: adding to __builtins__

Consider the following script (I need it under Python 2.2, where True and
False are undefined):

--- begin truefalse.py --

__builtins__.True=1
__builtins__.False=0 

print True,False

--- end truefalse.py --


It works:

$ python truefalse.py
1 0

However, if I import the script I have an AttributeError:

python
Python 2.2 (#1, Apr 12 2002, 15:29:57)
[GCC 2.96 20000731 (Red Hat Linux 7.2 2.96-109)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import truefalse
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "truefalse.py", line 3, in ?
    __builtins__.True=1
AttributeError: 'dict' object has no attribute 'True'

What's happening and is there a workaround ?

TIA,

                                 Michele
