I agree that the implicit acquisition of variables is
an ugly thing, but in practis I never had any problems
with it.

I don't agree on the later TAL exempel looking more understandable
than the DTML. To me the DTML looks more like programming code
which is something that I find easier to understand and read.

But I also understand that this is a matter of coding style and
taste. There is simply not a question of what's right or wrong.
(So IMHO there's no point in turning this in to a religious issue ;-)

The problem for me is that Zope developement lately has
only been focused on TAL. That's why I fell that I need to
raise my voise in favor for DTML, which after alote of
of fighting with TAL and METAL is my choise.

In my role as an consultant I have found that I do profit
more from using DTML than TAL. That's also partly because
I use Easy Publisher, which was designed with DTML as primary
markup language.
