Plenty of templating systems allow Model-View separation. Not all
*enforce* it, but this is a matter of philosophy [1], not an indicator
that a template system is good or bad.

Some templating systems (e.g. Nevow.Renderer, PyMeld and HMTLTemplate)
additionally separate presentation logic from markup via an approach
that's strongly reminiscent of Apple-style MVC, where the View layer
consists purely of GUI widget/template node instances and the
Controller layer contains code for (1) manipulating these objects and
(2) connecting to the Model layer.

have a good rammy now and again. Any competent developer will
automatically build a well-layered system, and no amount of nannying
is going to save an incompetent developer from themselves.
