Shoot.  I added __file__ to try and match the behavior of the standard 
interpreter, which DOES define such names in the script's namespace.  This was 
reported as a bug by Vivian a few days ago.  I'll try to look into Jorgen's 
report in more detail tonight, and at least find what the proper solution is.

I do think that, since Python determines that __file__ IS always defined in 
the execution namespace of a script, we should certainly declare it.
