Re: [Rails-devel] Some (multi-)undo related bugs

Turn-based boardgames are effectively state machines.  I'm not sure I
can think of a model object that should be stateless.

Certain parts of the view (in an MVC world) can and should be
stateless, but the model *is* the state of the application (read:
game).

[EV] Of course there is always some form of state behind a model, but often
it is not a single state. For instance, the views that give you a list of
available trains, or the player worth, or a share percentage, have models
that depend on some calculated value, which is not an independent state
itself.
