I just want to be sure a template is loaded only once in a page but if, for example, I include a template into itself, also all templates included by this template are recurrently loaded.
I tried to track this using a simple trick (this code for example is in column1.tpl):

{if is_set( $loaded )|not()}
        {def $loaded=true}
        {include uri='design:column1.tpl'}
{/if}

but is seems that <i>visibility</i> of $loaded variable is limited to this template and when it is reloaded it <i>is_set</i> no more.

Any suggestion?

HEEEEEEEELP!

I really cannot understand why it works (but it works).

This one:

{set-block scope=global variable=loaded}true{/set-block}
{if is_set( $loaded )}
        {include uri=concat('design:section', $node.object.section_id, '/column1.tpl')}
{/if}

The first time the template is loaded variable $loaded is correctly set, subsequent times it does not.
Is it a <i>feature</i>? (Or a bug?) ;-)

Nice try! :-)
Unfortunately $module_result is not available in overridden templates, so it is not useful for me at this time, since I need to know it in a override template.
