it's very simple and very basic... ClauseAdapter does not work.

heres an entirely valid SA expression:
subq = t2.select().alias('subq')
s = select([t1.c.col1, subq.c.col1], from_obj=[t1, subq,
t1.join(subq, t1.c.col1==subq.c.col2)])
the way the above works is, t1.join(subq) sends a message to the
enclosing Select to hide t1 and subq
i dont really understand why u need the ACP being so different to

putting all the choices (visit* vs convert; onentry/onexit;

After all, visitor pattern is twofold, a) Guide
heres the structure of: select(from_obj=[t1, t2, t1.join(t2)])
select +--- t1 -+
|--- t2 |
+--- join of t1/t2 ---+
t2 and t1 both have two parents, and there are two paths to each of t1
and t2 from the head select. so its not a tree in the

ACP has been entirely rewritten. if you can provide simple
