Not currently, and I tend to agree that it would be nice. The downside
is the templating language starts to look like a programming language,
and you loose your separation between presentation and logic, and that
way lies PHP... 8-)

You might, instead, consider pushing more back into the logic (controller
in MVC terms) - something like:

    page module:
        ctx.locals.labels = ['firstName', 'whatever']

    page template:
        <al-macro name="formlabel">
         <al-if expr="custhandle.handlerErrors[label_i.value()]">
          ...
         </al-if>
        </al-macro>

        <al-for iter="label_i" expr="labels">
         <al-expand name="formlabel">
        <al-for>
