------------------------------------------------------------------
DTML METHOD: period_begin
Selects a set of dates in the past 41 days that are either the
first day of the month or a Sunday. Returns the list.

<dtml-call "REQUEST.set('first_day', ZopeTime() )">
<dtml-call "REQUEST.set('to_day', ZopeTime() )">
<dtml-call "REQUEST.set('day_list', [])">

  <dtml-in "_.range(0,40)">
    <dtml-call "REQUEST.set('rpt_date', first_day -
_['sequence-item'])">

     <dtml-if "rpt_date.lessThanEqualTo( to_day )">
       <dtml-if "(rpt_date.day()==1) or rpt_date.dow()==0">
          <dtml-call "day_list.append(rpt_date.strftime('%Y / %m
/ %d'))">
       </dtml-if>
     </dtml-if>

  </dtml-in>

<dtml-return day_list>

-------------------------------------------------------
DTML METHOD: add_weekly
Input form to report weekly activities. 


<dtml-call "REQUEST.set('day_list', period_begin)">
<dtml-call "REQUEST.set('done_list', [])">

<dtml-in "objectValues(['DTML Document'])">
  <dtml-if "doc_type == 'weekly'">
     <dtml-call "done_list.append(week_begin.strftime('%Y / %m /
%d'))">
  </dtml-if>
</dtml-in>

<dtml-call day_list>


<dtml-in done_list>
   <dtml-if "_['sequence-item'] in day_list">
     <dtml-call "day_list.remove(_['sequence-item'])">
   </dtml-if>
</dtml-in>

....
more code here that uses day_list in a <SELECT></SELECT> and
takes more form input.
...


Is this a bug or should I clean up my code??? <s>
