Since that's mondo obscure, let's point to your explanation:

That's especially worth reading because of Guido's profusely apologetic
response <wink -- "Too bad.">.

I don't really know about Python Script, I've been talking about what
Python's warnings module does.  Perhaps you could use the Id of the script
as __name__ after Id.replace('.', '-') (i.e., get rid of the dots)?  Or it
*looks* like you could leave name None, but set '__file__' to something
(non-None) explicitly.
