-# What should be done, but isn't currently:
-#
-# broquaint> Another Cat question - if I want to have arbitrary things highlighted is pushing things through a View at all costs terribly wrong?
-# broquaint> e.g modifying this slightly to highlight anything (or arrays of anything) http://github.com/broquaint/Gitalist/blob/a7cc1ede5f9729465bb53da9c3a8b300a3aa8a0a/lib/Gitalist/View/SyntaxHighlight.pm
-#       t0m> no, that's totally fine.. I'd tend to push the rendering logic into a model, so you end up doing something like: $c->model('SyntaxDriver')->highlight_all($stuff, $c->view('SyntaxHighlight'));
-# broquaint> I'm thinking it's a bad idea because the Controller needs to munge data such that the View knows what to do
-# broquaint> You just blew my mind ;)
-#       t0m> ^^ That works _much_ better if you split up your view methods into process & render..
-#       t0m> ala TT..
-#       t0m> i.e. I'd have 'highlight this scalar' as the ->render method in the view..
-#       t0m> And then the 'default' thing (i.e. process method) will do that and shove the output in the body..
-#       t0m> but then you can write foreach my $thing (@things) { push(@highlighted_things, $c->view('SyntaxHighlight')->render($thing)); }
-#       t0m> and then I'd move that ^^ loop down into a model which actually knows about / abstracts walking the data structures concerned..
-#       t0m> But splitting render and process is the most important bit.. :) Otherwise you need to jump through hoops to render things that don't fit 'nicely' into the bits of stash / body that the view uses by 'default'
-#       t0m> I wouldn't kill you for putting the structure walking code in the view given you're walking simple arrays / hashes.. It becomes more important if you have a more complex visitor..
-#       t0m> (I use Visitor in the design patterns sense)
-#       t0m> As the visitor is responsible for walking the structure, delegating to the ->render call in the view which is responsible for actually mangling the content..
