Well spotted, you're not wrong.
That comes about because this is an as yet incomplete modification of an old subroutine with different goals. The bugs I encountered meant that I haven't gotten around to trying finishing the modifications.
But that has nothing to do with the error, as they are reproduced by this simplification: #! perl -slw
use strict;
use threads;
use threads::shared;
sub test {
my @results :shared;
async {
@results = 1 .. 10;
}->join;
print "@results";
return @results;
}
print test();
__END__
C:\test>junk50
1 2 3 4 5 6 7 8 9 10

I didn't switch to this as my example because I could not reproduce the circumstances of the "modification of a readonly value" with this.

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).
