hello monks, i'm using HTML::Template and TMPL_LOOP. i think i don't need a more complex templating system, there are only two little things at the moment i miss with this module. suppose i have data like: 
my $data = {
  name => 'name',
  id => 1,
  categories => [
    { id => 1, title => 'projects', ...},
    { id => 2, title => 'index', ...},
  ],
};

and the template: 
<TMPL_VAR NAME=ID>: <TMPL_VAR NAME=NAME><br>
<TMPL_LOOP NAME=CATEGORIES>
<TMPL_VAR NAME=ID>/<TMPL_VAR NAME=TITLE> |
</TMPL_LOOP>

[download]
then it outputs: 
1: name<br>
1/projects | 2/index |

first thing is: i only want one pipe | between the items, like in perl join " | ", @$items.
do you know any way to do that with HTML::Template?

the second thing: i'd like to be able to control the order of the items from the template (reason: the code is part of a kind of framework or CMS, and i don't want to hardcode it).

what i've done for the second problem:

i added a tag: <TMPL_VAR NAME=SET_REVERSE> which has to be inside of the loop. before i generate the template i use the query()-function to detect if the tag SET_REVERSE is in that loop, and then i reverse the list. 
foreach my $key (keys %$result) {
        if ($self->template()->query( name => $key) eq 'LOOP') {
                if ($self->template()->query( name => [$key, 'SET_REVE
+RSE'])) {
                        @{$result->{$key}} = reverse @{$result->{$key}
+};
                }
        }
}

this seems to work fine (i'm working only with one level deep data structures, fortunately). but it seems unelegant. do i need a different templating system? anyone can recommend one? or does this look reasonable to you?
thanks for any comments...
