It would be better if you did:

   package MyApp::C::Test;
   use base 'Catalyst::Controller';
   __PACKAGE__->mk_accessors(qw/attr somethingelse whatever/);
               # ^^ important!

   sub an_action :Whatever {
      my ($self, $c, @args) = @_;
      my $attr = $self->attr;                 # get
      $self->somethingelse('something else'); # set
   }

You can set them via the config file as above:

   Controller::Test:
     attr: foo
     whatever: bar

See the Class::Accessor documentation for full details on how these
accessors work.

It works.  Views, Models, and Controllers are all Components.
Theoretically you can have components that aren't M/V/C, but I've never
done that.
