[Zope] sqltest op=like problems

[alex@quad.com.ar]

uhmm just figured out a very dirty solution:

 SELECT * FROM table
 <dtml-sqlgroup where>
   <dtml-if terminal>
   <dtml-let terminal="'%' + terminal +'%'">
   <dtml-sqltest terminal op=like type=string>
   </dtml-let>
   </dtml-if>
...and so on...

it's dirty, but gets the job done... I'd still prefer a patch to dtml-let
any opinions?
