Well one way to do this would be something like this:

<python25.py>

def all(iterable):
         for element in iterable:
             if not element:
                 return False
         return True

</python25.py>

And combine that with the code that Robert gave you. I'm not sure of
the exact syntax, but I would think you could do an IF statement that
creates the custom definition and returns it if Python 2.4 or less is
installed and return the normal version for 2.5 if it is installed.
