more relation/collection state confusion when using session.flush([only_one_of_the_objects]). time to deprecate ?

Testcase is in the attachment. I'll be glad to help if you point me.

I'm considering as a solution here to remove the flush([objects](objects)) feature in 0.6. There should be no use case for it.

1d3185139a923fa1a1998d4498748d8f49278ac0 allows you to properly reset the state of parent.children:

session.flush([child](child))
session.expire(parent, ['children']('children'))

assert parent.children == [child](child), "%r != %r" % (parent.children, [child](child))

but seriously, try to not use flush([obj](obj)). it makes no sense to use it on a single object in the midst of an interconnected graph of dependencies.

we've agreed on the deprecation, that's in b84c3b34694f36255e203af5a9d531ff89464bdc.
