I use HTML::Template to generate webpages. An annoyance of mine has always been needing to collect hashrefs from a DBI statement handler into an array so I can use the information in loops. I finally broke down and wrote this module. Yes, I am aware of $sth->fetchall_hashref. Unfortunately, this is quite memory intensive if there is a lot of data to be fetched. I hope someone else finds this module useful. 
package Tie::STHRows;

use base Tie::Array;

sub TIEARRAY {
  my $class = shift;
  my $sth = shift;
  die "You must pass a statement handler!" unless ref($sth) eq "DBI::s
+t";
  my %row;
  $sth->bind_columns( \( @row{ @{$sth->{NAME_lc} } } ));
  bless ([$sth,\%row],$class);  
}

sub FETCH {
  my $self = shift;
  $self->[0]->fetch;
  return +{ %{$self->[1]} }; # per tye's suggestion
}

sub FETCHSIZE {
  ${+shift}[0]->rows;
};

sub DESTROY {
  ${+shift}[0]->finish;
}

1;

__DATA__
sample snippet for how it works:

$sth = $dbh->prepare(...);
$sth->execute;
tie @loopdata, Tie::STHRows, $sth;
$template->param(LOOPDATA => \@loopdata);

and your template:

<TMPL_LOOP NAME=LOOPDATA>
...
</TMPL_LOOP>
