I think I'm with you on this one, but the syntax threw me for a bit of a loop at first glance. Basically, the "shorthand" syntax shouldn't look too "URL-like". Perhaps this:

this.namespace('admin', function () {
  this.match('i_use_another_controller', '::www#action');
  this.match('i_use_another_namespace', '::another_namespace::my_cont#action');
});

Which rewritten in option form, translates into:

this.namespace('admin', function () {
  this.match('i_use_another_controller', { namespace: '', controller: 'www', action: 'action' });
  this.match('i_use_another_namespace', { namespace: 'another_namespace', controller: 'my_cont', action: 'action' });
});

It boils down to adding a syntax to specify namespaces in shorthand notation, and then using fully-qualified forms of those to "back-out" namespaces in the routes.

I'm going to mull over the syntax a bit, and see if I settle on something that feels right. Let me know if you have any ideas.

Cool, either way is good :) I'm using my patch for a site at the moment once we've got this sorted I'll amend my dependant code to match :)

You had any thoughts on this one?
