oh MAN.....
well, this is just great.
if I just add the attribute dictionary to the object, it creates
circular references, then people complain that their objects dont get
removed from the identity map when they fall out of scope.
if I remove the circular reference by using a weakref, now Pickle
doesnt work.
it looks like im going to have to go back to the old way, where the
so-called "magic" (its just a dictionary stored at
obj._managed_attributes) is mapped to objects via a separate weak key
dictionary somewhere.
I just found a quick way to stick that on, I think rev 1259 should
solve the issue.

Hi,
I use to save one of my model objects in the myghty session (User
object).
This no longer works after updating to the lastest svn.
I'm assuming that weakref usage is causing this which is all fine.
Is there a way to remove all SA magic stuff from my objects after
SA has loaded it from the db.
So I can still do eg.
user = User.select_by(login='mylogin', password='mypassword')
objectstore.worry_not_about(user)
Which leaves my user object as a simple python object with
attributes and nothing else.
This is also useful because I would like to use my model objects as
DTO or parameter objects to methods but don't want SA to think that
changes to it should be persisted.
Thanks
