This is why this sort of controller extension should probably be a role
using Moose rather than a base class.

However, role application and multiple inheritance -are- basically
isomorphic for a lot of purposes; the difference is it's much easier to
shoot yourself in the head with multiple inheritance.

Which is probably why it's not popular - people are scared of powerful tools
that can bite :)
