This can be avoided if you "prepare" a namespace and pass it to the 
template, this way the template doesn't need to call methods.

I've written a simple page class for doing this, but it's also possible 
TTW from a Python script:

   names = {'foo': 'bar'}
   template = context.a_page_template
   return template.pt_render(extra_context=names)

Of course you can still use Python expressions if needed.
