If you're not already familiar with collections.namedtuple, have a look at it, as it sounds like just naming the fields may be all that you need. You can also subclass it further to add methods if desired. > However, if the method returns one element of the collection, how can > one enable introspection for users of IDE's that the resulting reference > is of type A, and therefor has A's fields? > > For example: > col = (Class(..), Class(...)) > item = col[0] > > Introspection will now enumerate item as an instance of Class, providing > its fields.

I think that's going to depend heavily on the specific IDE being used, but for general usage you might consider using PEP 484 type annotations; I know that at least PyCharm supports their use for type hinting. -- https://mail.python.org/mailman/listinfo/python-list
