thanks for the response, but i was really looking for a bit more detail.
To be precise - why the ':' after the sort?
'%players.sort' calls the 'sort' method/sub on the hash '%players'.
'{.value}' runs '.value' on $_ at some point. But when?
So once again, what is the ':' doing? How else

the first line creates a hash,
the second line sorts the hash values into an array.
the third loops thru the array values printing one array member per line

Here's a solution to Scripting Games #2. Script and data file attached.
The algorithm closely follows the published solution by the perl expert. Here
is the model solution
use 5.010;
use strict;
use warnings;
use List::Util qw(sum);
my %score;
open(my $fh, , C:/Scripts/skaters.txt) or die;
Richard ():
use v6;
my %players;
my $scores = open('./skaters.txt', :r) or die $!;
for =$scores {
my ($name,@list) = .split /\,/;
%players{$name} = ([+] @list.sort[2..6]) / 5;
};
my @ranking = %players.sort: { .value };
for Gold Silver Bronze - $m {
given pop @ranking {
say $m
