Alternatively, if you want/need to keep the Math::BigInt object intact, you can use threads::shared::shared_clone: use strict;
use threads;
use threads::shared;
use Math::BigInt;
use Data::Dump qw[ pp ];
use feature qw(say);
my @numbers = ( 1 .. 10 );
my %result : shared;
my @threads = map {
threads->create( \&process, $_ );
} @numbers;
$_->join for @threads;
for my $key ( sort{ $a <=> $b } keys %result ) {
say "$key : ", $result{ $key }, ' => ', $result{ $key }->bstr;
}
sub process {
my $number = shift;
my $factorial = factorial($number);
lock %result;
$result{$number} = shared_clone( $factorial ); ## clone the object
}
sub factorial {
my $number = shift;
Math::BigInt->bfac($number);
}

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).

are good places to start.
