Template inheritance as done by Django is ill-defined and I can
explain more.
You can do
{{extend 'another_template'}}
You can
{{include 'another_template'}}
You can create functions to define blocks before {{extend ...}}. This
is explained in the manual.

Yes if:
1) you define the function in models or
2) you define the funciton in controller and pass it to the view or
3) you import the function from the view
4) you create the function in the view {{def f(a)}}<h1>Helloe {{=a}}</
h1>{{return}}

Yes {{=XML(fragment)}}

You can do most of this this. In controller place
def mycaller(f):
before_controller()
d=f()
after_controller()
if isinstance(d,dict): d=response.render(d)
after_view()
response._caller=mycaller
You can still do before request and after request using wsgi
middleware.
I apologize for my sketchy responses but I am on vacation and I have
limited connectivity. I suggest you ask your questions again in April.
