Hi Roger,

   Thank you for spotting that. That works as expected:

----

  OUTER: I AM THE OUTER VAR
 
     INNER: I AM THE INNER VAR
     INSIDE OUT: I AM THE OUTER VAR

----

   My next step was to then remove the outer_var from the outer_loop in the
template, but still use it in the inner_loop in the template (as indicated in
the changelog):

<TMPL_LOOP OUTER_LOOP>
   <!-- no outer_var here anymore -->
   <TMPL_LOOP INNER_LOOP>
      INNER: <TMPL_VAR INNER_VAR>
      INSIDE OUT: <TMPL_VAR OUTER_VAR>
   </TMPL_LOOP>
</TMPL_LOOP>

but that does not work as expected:

HTML::Template : Attempt to set nonexistent parameter 'outer_var' - this
parameter name doesn't match any declarations in the template file :
(die_on_bad_params => 1) at
/usr/local/lib/perl5/site_perl/5.8.5/HTML/Template.pm 3068 at at test.pl line 30

It seems that unused outer_loop variables do not work in inner_loops as
indicated in the changelog.

Thanks,
Alex
