Haskell on a Horse: a new web framework based on arrows and continuations

<i>To deal with high demand, the server is being restarted once a minute.</i><p>Wow, they really are trying to imitate Rails.

"Haskell on Horseback" would have more of a ring to it.

Does this support templating, data models, etc? How far removed is this from a "traditional" MVC web framework and how can on-a-horse be applied in real business? Does it have built-in support for ajax responses, dynamic partial rendering etc?
