The problem is that Catalyst apps do their setup once at initialisation time, 
so just reloading the changed code isn't always sufficient - as such the best 
way to get a clean sheet after a change is a full reload.

You're welcome to try Apache::Reload, Module::Refresh and friends - I believe 
provided you're using DBIx::Class rather than Class::DBI they work pretty 
well, but bear in mind things like config changes and model setup events will 
still need a full re-init to re-fire.
