Well, the first thing I'd do is suggest that if possible you just don't 
put all 200 things into the loop. That would save on your processing if 
you didn't have to create the big loop to begin with.

But if you needed them in the loop in some places but didn't want to 
display them in others, you can use the __counter__ loop context var 
combined with HTML::Template::Expr.

<tmpl_loop outbounds>
   <tmpl_if expr="__counter__ <= 15">
     ...
   </tmpl_if>
</tmpl_loop>

It's not possible with just HTML::Template, but HTML::Template::Expr 
should help you get there.
