Ah, that is more what I am after. :-)

Had started looking at Velocity and if Cheetah is a similar thing for
Python, then it is perhaps closer to what I am after. Not being able
to find iteration etc in Cheetah documentation threw me and I hadn't
had a chance to sift through the code as yet.

When you say one can to $myList[3:15], does that mean that for
simple array access one can still say $myList[3]. I wasn't too keen
on the $myList.3 mentioned in documentation.

Anyway, while I think more about all this stuff, I will probably in the short
term implement support which gives equivalent interface to mod_python
in Apache. A lot of the template systems for Python have mod_python
wrappers, so if done correctly most template systems might be able to
be easily plugged in and people can use what they want. At least I think
that should work. :-)

When I get a chance, will also look more at Cheetah itself as the documentation
may not be the best guide right now as to what it can do.
