If you use

   <dtml-with x mapping>
     <dtml-var foo>
   </dtml-with>

You will get the result you want.

For the other stuff, look in DocumentTemplate/pDocumentTemplate.py. The 
python code is pretty clear, although the C version is what is normally 
used in Zope.

Otherwise, see DocumentTemplate/DT_Util.py and DT_With.py, or see how it 
is done in ZPatterns in Expressions.py.


By the way, I notice you posted this to zope@zope.org and 
zope-dev@zope.org. If you look in the standard footer of each email from 
both lists, you'll see this:
