sometimes i solve such flat-namespace-collisions by adding inner level
of syntax in argument values + parsing them, e.g. for command line
strings:
myapp mainarg1=v1 mainarg2=v2 sqlite='arg1:val1,arg2:val2'.
this is somewhat ugly too, and is even uglier to extend to more

i am doing testing about these links and nodes.
For each testcase i have one constant set of nodes, and then trying
different scenarios with various combination of links.
Each scenario creates all database stuff a new - db, metadata,
mappers, session - and after te
g'day
i have Links, pointing to Nodes.
Adding just Links to session + flush() works as expected - both Links
and Nodes got saved.
Doing session.close() although does not always detach all related
objects, i.e. sometimes some Nodes stay with _session_id on them
after session is long gone.

i have a problem with this 2424, before that was ok.
As i can't separate a short case now, here the conditions:
multi-table-inheritance, polymorphic. Nothing else too fancy.
table_Entity has primary db_id,
one thing u can do is to replace some/all {} dicts with
util.OrderedDict (and util.Set with util.OrderdSet) - including your
owns!. u would be able to compare things easier then.
or, try going backward to some rev that works, and check changes
inbetween.

ok, that solves some things, i won't need those ultra-explicit

The other problem remains:
union's mechanism for corresponding_column() takes ownership of all
columns mentioned in the WHERE, regardless if they are from a table

with the simpler

Problem appears if A->B->C, A references B, B-mapper is polymorphic

For simple table==class, the link is 1:1.
For multi-table-
how much OO u want?
There is SA, which has ORM layer over sql, so can become a somewhat
object persistency.
There are turboentity/activemapper, currently joining together, which
are simple declarative layer on top of SA.
Then here is this 'sawrapper' of mine, which is also declarative and
wide

which revision are u using?
eventuly check for remaining print's somewhere:
grep -R "^ *print" /sqlalchemy
or
grep -R "^[^#]*print" /sqlalchemy
