Note that you may omit quotes on hash keys, but not on values.

If you use strict.  Which is what you should do anyway ;-)

Just build a hash containing references to all your data structures:

    %CSI = (ToDay => 'Sep 23, 2004'; PageTitle => 'Not doing so well');
    @array = ([ LastName => 'Smith',    FirstName => 'John', ID => 'BR549' ]
             ,[ LastName => 'Anderson', FirstName => 'Rod',  ID => 'BR007' ]
             );

    $sut->process($filename
                 ,{'CSI'       => \%CSI
                  ,'array'     => \@array
                  }
                 );

...and in your template you can have things like:

At [% CSI.ToDay %] [% array.0.FirstName %] [% array.0.LastName %] was
   [% CSI.PageTitle %].
