In 5.6.0 on AIX, I did:

#!/usr/bin/perl
use Data::Dumper;
 
my $test = Test->new;
$test->xyz;
my $a = $test->test(1);
my $b = \$test->test(2);
print Dumper( $test->test(3) );
print Dumper( $a );
print Dumper( $b );
exit 0;
 
package Test;
use strict;
sub new { return bless {}, shift; }
sub xyz { (1..3) }
sub test { }
1;
 
__END__

-----

$VAR1 = bless( {}, 'Test' );
$VAR2 = 3;
$VAR1 = undef;
$VAR1 = \2;

It looks like the implicit return in list context, barring no other statements, is @_. Having an intervening statement didn't do anything.

The idea is a little like C++ templates, except not quite so brain-meltingly complicated. -- TheDamian, Exegesis 6
