Try it. :P
No, I think you can't. Someone correct me if I'm wrong.
$content.visitor_numbers asks for an attribute in content. Think of
templates as python functions (that's what they become after all). Your
index function receives a visitor_numbers argument, but does it have
an attribute called visitor_numbers? The way to set an attribute to a
template is by using $var.

You can avoid doing that.
You could do something like the following code. Be aware that I didn't
test it, and it looks like too much magic :) Here it is:
-- layout.html
$def with (content, visitor_numbers)
<p>Numbers: $visitor_numbers</p>
<p>$:content</p>
-- pages.py
import web
class RenderInContext:
def __init__(self, dir = 'templates/', base, **base_args):
self.render = web.template.render(dir)
self.base = base
self.base_args = base_args
def __getattr__(self, tpl):
def f(**tpl_args):
content = getattr(self.render, tpl)(**tpl_args)
return getattr(self.render, self.base)(content, **base_args)
return f
render_in_context = RenderInContext('templates/', base = 'layout',
visitor_numbers = '20')
render_in_context.index(foo = bar)

No problemo :)
