The above is hardcoded, as I said the reference is dynamic.
i.e. application.page[ url.page ]
Which translates into application.page["index.blog"]

I realize that, I was only showing what it would/could evaluate to.

That�s why I said it could not work.
Anyway, I could do evaluate("application.page." & url.page) I could work
with that, but there are still complications then, when one level does not
exist for example.
It's a bit complicated, and I probably did not explain myself very well, I
should have waited before consulting the list.
