[Templates] can't sort a list with only one member

Hi tt fans,

If I try to sort a list with only one value, that value gets lost.  Here is a simple 
example which shows the problem.

<begin code>
use strict;
use Template;

sub get_colors {
   my @items = ("red");
   return @items;
}
{
    my $template = Template->new;
    $template->process( \*DATA,{colors => \&get_colors}) ||
         die "No process: ", $template->error();
}

__DATA__
Works fine:
[%FOREACH color = colors %]
hello : [%color%]
[%END%]

Can't sort (outputs nothing):
[%FOREACH color = colors.sort %]
hello : [%color%]
[%END%]
<end code>

Is this a known subtlety?

regards,

Brian
