[Catalyst] How to get default()-like behavior outside of the Root controller

    package MyApp::Admin;
    sub default : Chained('base') PathPart('') { ... }
    package MyApp::Survey;
    sub default : Chained('base') PathPart('') { ... }

Note how you don’t specify any particular number of arguments. So it
will match any number of trailing URL segments.

I *think* this will work. I haven’t tried it.

However, contrary to what you claimed, splitting the app into multiple
Cat apps joined together at the PSGI level *will* also work just fine.
That will lead to requests for /admin/* always being dispatched to
MyApp::Admin – which gets to have its own MyApp::Admin::Controller::Root
with a `default` action that applies only to it. Likewise requests for
/survey/* will always be dispatched to MyApp::Survey which equally has
its own root controller with a `default` action that applies only to it.
If the parts of your app are not closely related, this will be a more
natural structure.
