The use case is the example from JIRA issue.

e.g.
All our restrictions are held in Module, but that's mostly impl detail.
The way we expose that is via proper visitor pattern.

e.g.
A user can provide ScanningMetaData on-the-fly,
and we should take that in account when:
* re-creating old serialized AR
* creating AR at runtime

Not to mention resources lookup is *the* use-case where you need to apply visitor pattern.

OK, this could be made optional.

That's too simplistic.
You should have a proper abstraction.

I don't like to say this, but I'll still go ahead,
Papaki as it's currently in the trunk, is complete re-invent of the wheel.
Standalone argument doesn't convince me.

And I spent the whole week looking at it and thinking about it how to best integrate it with Deployers,
only to realize that complete re-write is what we should do.

Here is my version of it, which can be quite easily integrated with Deployers,
plus it uses all of the abstraction that are already under JBoss umbrella:
* Reflect -- abstraction between JDK Introspection and Javassist
* MDR - simplifying lookup via Signature
* VFS - resources lookup abstraction and visitor pattern
* ClassLoading - exact class resources visitor pattern
