Expanding on what mst said, keep in mind that plugins are reserved for
things that need to affect the request cycle.  If you just need some
functionality, write a regular module.  If it needs $c, pass in $c.
Component base classes are also possible, and are a better approach
than plugins.  (See C::Plugin::FormBuilder
vs. C::Controller::FormBuilder.  Both are on CPAN so you can compare
the approaches.)

Finally, phaylon's Extending Catalyst guide:

TMTOWTDI, but your way is rather unconventional.  Identifiers should
be lowercase (%karma_for), constants should be uppercase
($SECRET_OF_THE_UNIVERSE), and modules should be CamelCase
(MyApp::SomeThing).  Anything else will make people like mst mad
because it's really really ugly.

Hope this helps.
