... 'is' ... is overkill ...
I strongly agree! What's the point of bringing Scalar::Util::refaddr() et al to the party when == != (and all the other numeric comparators, in the unlikely event they would be of any use) seem to manage just fine:
c:\@Work\Perl\monks>perl
use strict;
use warnings;
use Test::Simple tests => 4;
1..4
sub is { $_[0] == $_[1] }
my $x = 3;
my $y = 3;
my $x_ref = \$x;
my $test_ref_1 = \$x;
my $test_ref_2 = \$y;
ok( is($test_ref_1, $x_ref), 'is Same' );
ok( !is($test_ref_2, $x_ref), 'is Different' );
ok( $test_ref_1 == $x_ref, '==' );
ok( $test_ref_2 != $x_ref, '!=' );
__END__
ok 1 - is Same
ok 2 - is Different
ok 3 - ==
ok 4 - !=
