That's because Darren misread your request.  What he thought you'd written
is this:

  # pass everything in under the SUI key
  my $tt = Template->new();
  $tt->process("foo.tt2", { SUI => \%SUI })
   or die $tt->error;

Not

  # pass everything in as a top level
  my $tt = Template->new();
  $tt->process("foo.tt2", \%SUI )
   or die $tt->error;

What you really want to know in TT is a way of seeing every variable that
is defined in the stash at all.  I can't think of an easy way to do this
within TT.  You're not the first person to ask for this either (Tom Insam
asked about this a few months back iirc.)

From Perl space, this is fairly simply of course:

  # dump out what we've about to pass in
  use Data::Dumper;
  print STDERR Dumper(\%SUI);  # print to the apache log everything

  # pass everything in as a top level
  my $tt = Template->new();
  $tt->process("foo.tt2", \%SUI )
   or die $tt->error;

I hope that helps.

Mark.
