injecting "set" into 2.3's builtins?

I use sets a lot in my Python 2.3 code at work and have been using this
hideous import to make the future move to 2.4's set type transparent:

    try:
        x = set
    except NameError:
        from sets import Set as set
    else:
        del x

Of course, while it's transparent at one level (where sets are used) it's
not really transparent at another level (where the set object is defined).

I'm toying with the idea of adding this to the sitecustomize module at work:

    import sets
    import __builtin__
    __builtin__.set = sets.Set
    del sets, __builtin__

I'm wondering if others have tried it. If so, did it cause any problems?
I've not noticed any incompatibilities between the 2.3 and 2.4 versions of
set objects, but my use of them has been pretty straightforward.

Thanks,

Skip
