Hmmm, just feels "hacky" to me. Kostache simply provides Kostache::set() for setting data. Surely that isn't too bad, I mean you already have ViewModel::render() which is public. Sure you could go down the magic route of PHPDoc style stuff, but again it feels like too much magic.

In ViewModel::render_modeldata() you could easily just skip a few predefined methods, and this way you could provide classes that extend ViewModel a way to exclude methods too!

In other news I will be releasing a cleaner, less convoluted update to Beautiful View that I would love you to take a look at if you have some spare time.

Thank you for your input! As I said, the purpose of creating this was fun and learning! :-)
I had an array with some methodnames to exclude, but took it away - wanted to keep it as minimalistic as possible.
I'm looking forward to the Beautiful view update! I'll check it out!
