Yes, I know that, but with join() my question still relevant. What I
want to do is for given column name and an arbitrary SA query -
retrieve unambiguous reference to the actual column of that query with
priority to those columns, which are "closer" to the root SELECT.
So for SELECT foo.name, bar.name FROM foo LEFT JOIN bar ON ... and
column name "name", I would like to build a function, that would return
a reference to a column object for foo.name.
I found a way of doing this, using froms attribute and finding original
SELECT by walking down relations, listed in it. But I wonder if there
are better ways.
