Sorry, top posting...  

An other way is to think about it bottom up instead of top down

Instead of the parent app including the children packages, we could do :

package App::Foo;
use Dancer scope => qw(App);

It's a bit like in relational database where you say who your parent is, not who your children are.  

It Also avoids to change the parent package every time you add a child.  

Also it makes it possible to use dancer with more than one scope. Not why it would useful though :)

We should probably look at breadboard and catalyst, see how they do it. David, I think you have experience with catalyst?

And that brings up the fact that we should use a serious tool to handle dancer 'use' options. Can we try an enhanced sub::exporter or similar?
