This PEP has two proposals, which I think should be better separated.

1. Leave __name__ alone (without the '__main__' hack) so that relative 
imports work when executing scripts within packages.  My comment here is 
that I am fuzzy on the difference between __name__ and __file__ and why we 
would then need both.

2. Fix the 'main' self-knowledge problem introduced by fix 1.  The 
'counter-proposal' is only an alternative to this second proposal, as it 
agree with the first.  I had the same idea as Christian as a third 
alternative, but as a user would prefer the simplest invocation possible. 
I agree with Jim that multiple alternatives should be listed.

I think the '__main__' hack was both elegant and a wart, and agree that we 
should seriously consider a pair of coupled fixes.

Package scripts, relative imports, and main identification.
