Just to throw my 2c into the fray.
ZPT is an HTML/XML template language. But what does that mean, really?
IMHO. Template languages are data structure navigation languages, or
model navigating languages (EEEK, templates having direct access to the
model!). And the should avoid being turing-complet

index: and key: are particularly interesting, in that they use
different syntax for something that python conflates syntactically.
That is, an integer indexed reference looks exactly like a string

If DTML used TALES expressions, it would be just as clean as ZPT.
With the one caveat that ZPTs are valid XHTML, while DTML methods needn't
balance tags and needn't mark empty tags as such (i.e. "",
instead of ""). DTML tags can straddle HTML tags in
completely non-XML ways: ""; limiting the
