I'm not sure such automatic behavior is feasible.
Consider e.g. a template like
${conditionVariable?then(dateVariable?iso_local("Europe/Rome"),
"UNKNOWN")}
What would the automatic logic do if conditionVariable is null, but
dateVariable is set? Or the opposite? (Sure, we may construct equivalent
expressions for such cases - but it's really complex, and I don't believe
it's feasible in the *general* case).
