- More issues with [ticket:2932] first resolved in 0.9.2 where
using a column key of the form ``<tablename>_<columnname>``
matching that of an aliased column in the text would still not
match at the ORM level, which is ultimately due to a core
column-matching issue. Additional rules have been added so that the
column ``_label`` is taken into account when working with a
:class:`.TextAsFrom` construct or with literal columns.
