Getting child nodes "index" when using #children template processing.

Is it possible to get the “index” of the current child node being processed by a the #children macro?

ex:
#children(“articlesTable” “TopArticlesTemplate” “” “” “” “”)

inside my TopArticlesTemplate i would like to do something like

#if($sys.index < 6)
##do something
#end

$sys.index appears to only be available when publishing “slot” items… Is there some other way to get at this information?

Thanks.
