Re: [SMARTY-DEV] enhanced foreach loops

Very interesting idea... You could do {assign var=previous_call 
value=$message.backtrace[$smarty.foreach.backtrace.index + 1]} but it 
wouldn't work for associative arrays or objects.  I like it!  What would 
be the desired behavior of $smarty.foreach.NAME.next when on the last 
item?  A default value? NULL?
