In that case, I'd like to apply my patch to HTTPRequest.py.

The patch does not break backwards compatibility. It allows __getitem__ 
and __getattr__ to each raise appropriate exceptions, while maintaining 
the shared method body. The only down side is one extra method call when 
calling __getattr__.

Any objections to me checking this into the trunk?
