Yeah, this why I'm strongly biased toward this possibility.

Well, I'm not sure about that. But just in case most of people would like to
access records by field as well as by index, I would advocate for the
possibility that the Record instances would behave as similar as possible as
a tuple (or dictionary?). That include creating appropriate __str__() *and*
__repr__() methods as well as __getitem__() that supports both name fields
and indices. I'm not sure about whether providing an __getattr__() method
would ok, but for the sake of simplicity and in order to have (preferably)
only one way to do things, I would say no.
