- [feature] *Very limited* support for
inheriting mappers to be GC'ed when the class itself is deferenced. The mapper must not have its own table (i.e. single table inh only) without polymorphic attributes in place. This allows for the use case of creating a temporary subclass of a declarative mapped class, with no table or mapping directives of its own, to be garbage collected when dereferenced by a unit test. [ticket:2526]
