AFAIK, the polymorphic_identity value there is used:
a) for queries, to discriminate/switch between object-types
b) for inserts, to put _that value when inserting that object-type.
i.e. to me these values ought to be some consts, different for each
subtype in the hierarchy. As of sharing that

The case is somewhat strange but is working before that - a
polymorphic union of concrete inheritances where the root-table is
not included in the union (i.e. leafs only). If it gets included, the

g'day.
in the Aggregator i have mapper extension, that needs info from the
mapper like local-table and mapping/naming of column properties.
It used to hook on instrument_class() for that, but now the

available yet when mapper-extensions a

another thing noted, the collections instrumentation fails over old
python classes (not inheriting object), e.g.

it fails at _instrument_class(), because type(myX()) being

util.Ones can point to dict/set.

IMO u should not touch sys.path unless u really really have no other

aaah, u are _that_ new...
- use it instead of the __import__() func
- original python library reference of the version u use;
e.g.
i think there was .one() to return one and only one and die otherwise
i.e. match {1},
and first() or similar that allows match {0,1}.

not really. Frankly, i dont know much elixir, just some impressions.
elixir is sort of syntax sugar over SA, with very little
decision-making inside. It leaves all the decisions - the routine
ones too - to the programmer. At least thats how i got it.

well, i'm using them NPs just to have another (simpler) select_table.
otherwise anything query through primary_mapper starts off its own
select_table, which can be rather huge in my case.
if u can make the a query( primary_mapper, select_table) somehow
possible... i won't need separate NPs. Note

on the "generative" line:
- how would i prepack a select (or some other filtering) and give it
to a query() _later_?
e.g. i have some table.c.type == 'person', and i want to apply to
several queries?
i can store the expression, doing query.select(expr) each time.
Any other way? e.g. store a sele
