Do you think I can alter the type of the returned objects into lists
by doing some magic __metaclass__ = ListType stuff? It would work then!

not really, since a plain list cannot track changes you have made
to that list, and a plain list also does not enforce uniqueness
which is also pretty important when eager loading. why is PyObjC
expecting plain list() objects and not duck-typed lists ? not very
pythonic, maybe you should email them ? other than that, you can
work around it in your classes using overridden properties and
such, or across the board you can make a monkeypatch to the mapper
like this:
import sqlalchemy.mapping.mapper as mapper
old_instances = mapper.Mapper.instances
def instances(*args, **kwargs):
return list(old_instances(*args, **kwargs))
mapper.Mapper.instances = instances
however you will lose all ability to use objectstore.commit() with
those lists since they arent tracking history.
