To make this discussion complete, on the other hand, most of the time, it is a better idea to return array ref, instead of array, regardless whether the program is multi-threaded: (In this way, you don't need to worry about the context any more)
use strict;
use warnings;
use Data::Dumper;
use threads;
my $thr = threads->new(\&sub1);
my $ReturnData = $thr->join;
print Dumper($ReturnData);
$ReturnData = sub1();
print Dumper($ReturnData);
sub sub1
{
return ["Fifty-six", "foo", 23];
}
This prints:
$VAR1 = [
'Fifty-six',
'foo',
23
];
$VAR1 = [
'Fifty-six',
'foo',
23
];

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
