i'd suggest using another rendering engine then.  one of the biggest  
benefits / reasons for using TAL is that its a standard cross  
platform thing.

and you can just use functions to do what you want

tal:
<select name="perly">
  <option petal:repeat="a getHashrefSortedOnKeyValue 'myHash'"
  petal:attributes="value="a" petal:content="myHash/a" />
</select>

i think the code is something like:
	my %Personalized= (
		blah=> $var,
		getFunction=> \&function,
		getHashrefSortedOnKeyValue=> \&Path::To::function,
	);
	print $template->render( \%Personalized );

i'm a bit wrong on passing the data to a template to render - i  
acutally use an abstraction class to set it all up for me... all the  
info is in the main Petal spec
the only thing i don't like about doing that, is that perl doesn't  
really implement iterators/generators like Python -- i think i  
mentioned this before... and in python when you yeild results from an  
object its cleaner/less annoying to do than with perl

search cpan... be warned though, they're all made because PETAL is  
too perlish and not strictly TAL enough in its performance.
