…can spin whatever standard factories, getters, and withers
are needed, in response to Lookup requests.

Thus, normal content, like inner classes, methods,
interface bindings, and annotations, is all in an

The POJO may also carry snippets of code, in
the form of private static methods, which are
intended *only* for the Q-type.
