Just one more question,
what is the difference between,
${$score{ "fred" } }
and
${$score}{"fred"}
are they the samething?
No, they are not.
The first assumes a hash named %score, e.g.
my %score = ( fred => \ 5 );
where the value of the key 'fred' is a scalar reference.
The second assumes a hash reference named $score, e.g.
my $score = { fred => 5 };
