I used to have a templating framework that I was using
before I finally tried out Seaside, and then moved away
from templating. Just a few weeks ago, I dumped it from
my image - it never occurred to me that one might still
want templating, when using Seaside.

IIRC, it parsed a stream for %xxx%, and kept a
collection of offsets for each such spot. Then a
render call would be made with a dictionary supplying
the substitution strings. Somehow, a collection of
values would result in an iteration over a portion
of the file. Not surprisingly, building the data
for the rendering was a major headache.

I'll take a few moments to try and revive it, and fit
it into the suggested API. Another possibility is to
use the substitution parameter name as a getter method.
