...or, with a bit more complexity for `error checking'. Bit of a smartass, but it does copy/paste, and it does provide an example of named-ref style params :)

#!/usr/bin/perl

use warnings;
use strict;

my $need_work        = 10;
my $i_tried          = 0;
my $die_if_its_broke = 0;  # bool: true is fatal

while ( $need_work > $i_tried ) {

    $i_tried++;

    handle_error({
                   value        => $i_tried,
                   die_if_broke => $die_if_its_broke,
               });

    print "From main(), I've tried $i_tried\n";
}

sub handle_error {

    my $params          = shift;

    my $value_to_check  = $params->{ value };
    my $death           = $params->{ die_if_broke };

    my $error_condition = 5;

    if ( $value_to_check == $error_condition ) {

        die "Fatality!!: $!" if $death;
        
        open my $fh, ">", 'logfile.txt' 
            or die "Can't open the fscking file: $!";

        my $error_statement
          = "We've hit the error threshold " .
            ": $error_condition!\n";

        print $fh $error_statement;
    }
}
