I have already reported this to Jeremy. There are other instances
of 'from x import *' in function and class scope too, e.g.
some test() functions in the standard dist do this.

I am repeating myself here, but I think that this single change
will cause so many people to find their scripts are failing
that it is really not worth it. 

Better issue a warning than raise an exception here !
