I recently had a bug in a Web page where if we had a single digit day, Template Toolkit v2.08 was failing a conditional check to see if it matched its numeric equivalent. I suspect that this is caused by Template Toolkit using eq when an == is found in the document. This causes 3 == '03' to evaluate as false and violates the DWIM principle.

Is this a known issue, mentioned somewhere in the docs, or just a bug? Below is a short test script that demonstrates the problem.

#!/usr/bin/perl -w
use strict;
use Template;

my $template = Template->new;
my %data = (
    foo => 3,
    bar => '03' 
);

print "Perl results: ", $data{ foo } == $data{ bar }
    ? "match\n"
    : "no match\n";

$template->process( \*DATA, \%data );

__DATA__
Template results:  [% foo == bar ? 'match' : 'no match' %]

I fixed the problem in my code by forcing 'bar' to be numeric.

Template results:  [% foo == bar+0 ? 'match' : 'no match' %]
