Ok, another thing on the subject:
It looks like that does not work before a commit. Even a flush doesn't
help:
t1 = Tile(id=1)
t2 = Tile(id=2)
t3 = Tile(id=3)
t4 = Tile(id=4)
session.add_all([t1, t2, t3, t4])
session.flush()
assert t2.neighbors == [t1]
FAIL
I'd really like to use it before even a flush! :)
