We should include module-level doc comments that explain what this demonstrates, why it's useful, why special effort is needed (there's no static guarantee that all components are Clone) and what the caveats are (unregistered components aren't cloned).

Cool, I'll get on (I've not written an example before)

Let me know if you think I should make any changes to the example. I think it's a pretty good reference example of what you can do with the new API, though I'm curious if some sort of MapWorld<> API is reasonable as a better example.
