Well, if you're going to stick to it not being an option to make any
changes, the answer is "no".  However, you can make a little hack that
*does* work:

>>> from lazy import lazy
>>> a = lazy.b
No name 'b' defined, using default 777
>>> print a
777

Inside lazy.py, you define a class called lazy with a __getitem__()
method.
