How has support for MCE (Many-Core Engine) changed across recent Perl versions?

# Example of using MCE in Perl for parallel processing
use MCE::Shared; 
use MCE; 

my @data = (1..100); 
my $sum = 0; 

MCE->init { 
    MCE->say('Processing data in parallel...'); 
}; 

mce_loop(\@data, sub {
    my ($chunk_ref, $chunk_id) = @_;
    my $local_sum = 0; 
    $local_sum += $_ for @$chunk_ref; 
    MCE::Shared->add('sum', $local_sum); 
}); 

print "Total sum: $sum\n"; # Outputs the total sum of the numbers from 1 to 100
