Actually, the code above is not equivalent to what you described with the Kid template. This code is equivalent:
Kevin,
I've recreated this for your convenience.
This is with a shiny new project. I called it 'test', how imaginative.
The default controllers.py has been modifed thusly. I've left the original code in it but commented out.
== snip ==
import turbogears
from turbogears import controllers
class Root(controllers.Root ):
@turbogears.expose(html="test.templates.welcome")
def index(self):
return dict()
# import time
# return dict(now=time.ctime())
== snip ==
As you can see, instead of returning a dict that is populated with the 'time' attribute, I am now returning an empty dict. This causes an exception to be raised.
== snip ==
500 Internal error
Server got itself in trouble
Traceback (most recent call last):== snip ==

This is of course tracable to this line in the welcome.kid template:
== snip ==
<p>Your TurboGears server is running as of <span py:replace="now">now</span>.</p>
== snip ==
This is what I was referring to about the 'one too many attributes' scenario, and what I was considering to be non-pythonic from "a certain point of view".
The reverse (missing the variable in the template) also raises an exception, but as I said I think that one is understandable and is completely consistent with Python.
On to other issues.
