If you are trying to create a list variable which you then store as a
property field, try something like

<dtml-call "REQUEST.set('alist', [])">
<dtml-in "objectValues(['Folder'])">
  <dtml-call "alist.append(id)">
</dtml-in>

you can then store the variable 'alist' in a property field on a folder (in
this case 'somefolder'), eg.

<dtml-call "somefolder.manage_addProperty('alist', alist, 'lines')">

you can then access the list by:

<dtml-in "somefolder.alist">
  <dtml-var sequence-item><br>
</dtml-in>
