Not with a closure trait and without a flag, which I guess does
not count as elegant.
In Template Toolkit this is nice insofar as that the loop
iterator is available as an object in a variable, so you can say
IF loop.first ; ... ; END ;
but equally
IF NOT loop.first ; ... ; END ;
and similarly you can say
IF NOT loop.last ; ... ; END ;
to do something on all iterations but the ultimate.
