Perhaps another example will prove its uglyness.

 <dtml-if "REQUEST.has_key('some_value') and this().has_key(some_value) and
_[some_value] == 'a property value' and
AUTHENTICATED_USER.has_role('Manager')">
  <a href="a_url">
 </dtml-if>
  link text
 <dtml-if "REQUEST.has_key('some_value') and this().has_key(some_value) and
_[some_value] == 'a property value' and
AUTHENTICATED_USER.has_role('Manager')">
   </a>
 <dtml-else>
   (no link available)
 </dtml-if>


or

<dtml-if "REQUEST.has_key('some_value') and this().has_key(some_value) and
_[some_value] == 'a property value' and
AUTHENTICATED_USER.has_role('Manager')">
  <a href="a_url">
<dtml-always>
  link text
<dtml-else>
  (no link currently available)
<dtml-then>
  </a>
</dtml-if>

Now which looks cleaner?
