Get all the known objects that derive from a given sealed class.
Get all the known objects that derive from a given sealed class. It must be called after the case objects are defined, or else they will not be visible to the macro.
This will actually return all descendant objects that descend from the sealed class,
whether or not they were marked case object or not.
* Warning: This will not always work on inner classes. If you have a sealed class
hierarchy inside a trait, there will be no known objects if this is used inside the trait
itself. It should work in classes that descend from that trait. My recommendation is to
either stick to top-level classes or verify (manually or by testing) that you get all the
objects you expect.
(This is due to SI-7406.)
