I have to admit that the new "experimental" syntax has helped me break
some old habits and generate more expr="readable()" code.  Part of it's
due to the fact that now I can train Alpha to do some shortcuts
(autocomplete, yay!) and prevent me from doing the
less-understandable-shortcuts.

And now, even outside of my cozy li'l editors and inside the harsh
reality of <textarea>, I find myself entering:

<dtml-if name="green_eggs">
 <!--green eggs exists, lets check ham-->
 <dtml-if name="ham">
  <!--alright, ham too!  lets check the color-->
  <dtml-if expr="ham.color=='green'">
   <p style="color: green">Green eggs <em>and</em> ham!</p>
  <dtml-else>
   <dtml-with name="ham">
   <p style="color: &dtml-color;">Green eggs and 
   <em><dtml-var name="color"></em> ham. :(</p>
   </dtml-with>
  </dtml-if>
 </dtml-if>
</dtml-if>

Kinda purdy, ain't it? :)
