Qustion about ithreads join

[Taewoon Kwon]

Nowadays, I learn about perl ithreads, reading perlthrtut perldoc.

I tested a sample code in that document

#---code start
use threads;

$thr = threads->new(\&sub1);

@ReturnData = $thr->join;
print "Thread returned @ReturnData";

sub sub1 { return "Fifty-six", "foo", 2; }
#---code end
and result of above code was printing '2', not 'Fifty-six foo 2'.

As far as I know it should print the 'Fifty-six foo 2'.
Could somebody explain the result?

Platform I tested the code was ActiveState Perl v5.8.4 for windows, and
perl v5.8.1 built in Mac Os X. Both showed the same result.

sub sub1 { return "Fifty-six", "foo", 2; }
#---code end
and result of above code was printing '2', not 'Fifty-six foo 2'.

As far as I know it should print the 'Fifty-six foo 2'.
Could somebody explain the result?

@array = sub1();
print "In list context, the result is @array\n";
$scalar = sub1();
print "In scalar context, the result is $scalar\n";

You should not expect them to return the same results.
