I'm not really sure what people are getting at here - ctx.add_session_vars() 
simply controls which attributes of ctx.locals are pickled - I can't see
why you'd want to modify the return from session_vars() any way other
than via ctx.(add|del)_session_vars()?

If it's debugging, it's probably better just to put a bunch of writes
to sys.stderr in the page module, rather than modifying the template
(particularly with complex templates).
