It's not terribly important to this discussion that I mention this, but the and next bit is not part of what's confusing me. I understand this part of the idiom.

However, instead of doing this…

CHILD:
foreach my $child ( 0 .. $#names ) {
    my $pid = $pm->start($names[$child]) and next;

    # Child process...
}

…I would typically prefer to do this…

CHILD:
for my $child ( 0 .. $#names ) {
    my $pid = $pm->start($names[$child]);
    
    next CHILD if $pid != 0; # Parent process

    # Child process...
}

I think this is more in line with PBP, but I could be mistaken.
