- [feature] The "deferred declarative

reflection" system has been moved into the
declarative extension itself, using the
new DeferredReflection class.  This
class is now tested with both single
and joined table inheritance use cases.
[ticket:2485]
- [bug] The autoload_replace flag on Table,
when False, will cause any reflected foreign key
constraints which refer to already-declared
columns to be skipped, assuming that the
in-Python declared column will take over
the task of specifying in-Python ForeignKey
or ForeignKeyConstraint declarations.
