My 'pushpage' package is an attempt to make this the "standard" pattern
(pushpage templates don't have *any* top-level names available to them
(i.e., 'context', 'container', 'request', etc.) except those passed to
their '__call__' as keyword arguments (which traditional ZPT exposes
under 'options'):

  http://agendaless.com/Members/tseaver/software/pushpage

The templates can be used from within methods of view classes, and can
also be published as "pages" via ZCML with the help of a user-defined
callable which computes the keyword arguments.  E.g.:

      <pushpage:view
        for=".interfaces.ISomeContentInterface"
        name="somepage.html"
        permission="zope.Public"
        template="templates/sometemplate.pt"
        mapping=".somemodule,somefunction"
        layer="mylayer"
        />

In this example, 'somemodule.somefunction' returns the mapping which
'sometemplate' will use as its top-level namespace.  The callable is
passed 'context' and 'request' as arguments.
