Framework announcements should always come with sample code. Always. Talking about how great it is doesn't help me understand how it works.

The complete canonical example of the counter. Of course with the back button and browser fork working.

Launched with : nagare-admin serve-module counter.py:Counter counter ===============================================

  from nagare import presentation

  # A pure python Counter class
  class Counter:
    def __init__(self, v=0):
        self.v = v

    def increase(self):
        self.v += 1

    def decrease(self):
        self.v -= 1

  # Default HTML view on the Counter class
  @presentation.render_for(Counter)
  def render(self, h, *args):
    return h.div(
               h.p('Value: ', self.v),
               h.a('++').action(self.increase),
               ' | ',
               h.a('--').action(self.decrease)
           )

I always thought someone should clone Seaside in Python. Looks very intriguing.
