It would be nice if there would be the chance to mark states as final. Maybe by using sate :foo, is_final: true or somehow else...

This could be used to generate a method is_final? returning true if the object is n a final state.

It would be nice to also have some scopes to filter for objects in final and non-final state.

Mostly you don't want to do something only in one state but in a collection of states. This leads to code like where(workflow_state: ['foo', 'bar']). It would be very useful to name this kind of state combination.

This could be done by metadata: state :foo, groups: [:baz].
For every group there should be generated the same methods generated for states themselves. E.g. o.baz? should return true if o is in state :foo or in some other state referring to :baz.

Scopes (see #3) would be very useful too... Maybe this meachanism could/should even be used to implement #4.

There should be a scope for every workflow state

E.g.

workflow do
  state :foo do
    #...
  end
end

Should automatically define a scope foo in the respective class
