Yeah, you can use the REQUEST variable:

Here is the code you want (Again, it is tested):

<dtml-var standard_html_header>

   <dtml-call "REQUEST.set('l', [])">

   <dtml-in "['Admin', 'Help', 'Project']">
     <dtml-let x=sequence-item>
       <dtml-call "REQUEST.set('l', l + _[x].objectValues())">
     </dtml-let>
   </dtml-in>

   <dtml-in l>
     <dtml-var id><br>
   </dtml-in>

<dtml-var standard_html_footer>

Two interesting problems you had there. :)
If you want to do these type of things, you should learn Python. Once you 
understand the language, it becomes much easier to solve these type of issues.
