That shouldn't parse, because .split should not be looking for an
argument list. (And, in fact, STD rejects it.) You need one of:
my ($name,@list) = .split: /\,/;
my ($name,@list) = .

You need to be careful about what you mean here by "negative". If you mean
"match
a single character that is not in the list", then it is as Patrick said.

It is turning the method call into a list operator, essentially.
It's not the so-called indirect object syntax, or it would be written:
my @ranking = so

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

ack (or grep) ': {}' in Spec dir can give a lot of examples.

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
