In the article on HTML::Template at http://html-template.sourceforge.net/article.html, there is some sample code:

  foreach my $name (sort keys %fruit_data) {
    # get the color and shape from the data hash
    my ($color, $shape) = @{$fruit_data{$name}};
    
    # make a new row for this fruit - the keys are <TMPL_VAR> names
    # and the values are the values to fill in the template.
    my %row = ( 
               name => $name,
               color => $color,
               shape => $shape
              );

    # put this row into the loop by reference             
    push(@loop, \%row);
  }

... but I'm confused - this looks like (and testing seems to bear it out) that the contents of @loop will all be identical hashes (since they are all references to a single hash, %row).

Here's the code I used to check this:

print "Here we push a hash onto a list, modify the hash and push again
+\n";
my @list;
my %hash;

%hash = (
  val1 => 'foo',
  var2 => 'bar'
);
print "contents of \$hash\n";
foreach(keys %hash){
  print "$_  = $hash{$_}\n";
}
push(@list, \%hash);

my $key;
print "deref contents of \@list\n";
foreach(@list){
  foreach $key(keys %$_){
    print "$key = $$_{$key}\n";
  }
}

%hash = (
  val1 => 'bish',
  val2 => 'bash'
);
print "contents of \$hash\n";
foreach(keys %hash){
  print "$_ = $hash{$_}\n";
}
push(@list, \%hash);
print "deref contents of \@list\n";
foreach(@list){
  foreach $key(keys %$_){
    print "$key = $$_{$key}\n";
  }
}

Is the article wrong, or have I missed something?
