Hi Karol.
Please see the wiki: http://wiki.python.org/moin/SummerOfCode/
There are a bunch of ideas up there. If you want to hash out new
ideas, I suppose this list is as good as any. But please do some

Hello everyone.
I'm interested in the Python Software Foundation's Google Summer of Code
proposals.
What should I do?
1. Should I post my resume here?
2. List a few of the proposals that really interest me?
3. Explain why I feel qualified to contribute?
4. Who should I talk to?
Thanks for every

This is probably because we have a similar ambiguity in assignments:
the grammar says something like
exprlist ('=' exprlist)*
but what is actually desired is
