Generally, if it's a small, known, unlikely-to-change structure, I'd
use a tuple. For anything else I'd use a class, namedtuple or bunch.

However, pre-namedtuples I'd usually abstract away the field
referencing with indices and lambdas:

   name = 0
   role = 1
   name_role = lambda t: (t[name], t[role])

   name, role = name_role(record)

etc
