WSGI the hammer!  Must we necessarly have a nail here?

I think what's missing in this discussion is that templates are often
used to build but a small part of an result; a left toolbar, a menu,
perhaps even a row in a table -- but no more.  I think that the
requirements and design constraints involved make them so different from
full-fledged WSGI applications/filters that even thinking about them in
WSGI terms isn't helpful.

That said, I do like the idea of passing templates a WSGI ``environ`` in
addition to the input data that they should render; however, everything
else in WSGI doesn't seem particularly applicable.  The "composition" 
patterns are completely different.

Best,
