I do not think there was an agreement on whether to have this feature
or not. Based on the points raised by Doug, my personal opinion is
that we should have this feature along with the facility (which in my
opinion is a cool fallback when no other Pythonic way works) suggested
by Doug.  To keep the discussion moving for both the ideas, I am
sending a patch which addresses the nits pointed out by Doug on my
first patch.  I will hopefully find time during the holidays to work
on the feature suggested by Doug.
