Fair enough :)

I was a proponent of this system (C::P::Observable, for example), but
that unfortunately doesn't let you add arbitrary methods to the
application class.  Using roles will allow that.

Roles also let us apply plugins to instances instead of classes, if
desired.  For example:

   http://git.jrock.us/?p=Catalyst-Request-Pluggable.git;a=blob;f=t/lib/TestApp/Controller/Foo.pm;hb=HEAD

That example lets you apply roles to the request object at runtime; so
C<begin> can inspect the request, and (for example) apply the REST role
if the request is RESTful.  Very clean, so I think that's the way to go.

Oh, and apologies for the OT message!  beer, pie, Perl6 has too
much syntax!111!!1, etc.
