```# Scrabble distribution
our %letter_distribution = qw(
a 9  b 2  c 2  d 4
e 12 f 2  g 3  h 2
i 9  j 1  k 1  l 4
m 2  n 6  o 8  p 2
q 1  r 6  s 4  t 6
u 4  v 2  w 2  x 1
y 2  z 1
) ;

You never use this variable anywhere so why is it here?

```  sort { score_word(\$a) cmp score_word(\$b) }

score_word() returns a numeric value so that should be:

```  sort { score_word(\$a) <=> score_word(\$b) }

And if you used a Schwartzian Transform you wouldn't have as much overhead on all those subroutine calls.

```# search for matching words
my @possible_words =
map \$_->[ 1 ],
sort { \$a->[ 0 ] <=> \$b->[ 0 ] }
map length() == length( \$word_pattern ) && pattern_word( \$word_pat
+tern, \$_ ) ? [ score_word( \$_ ), \$_ ] : (),
@dictionary;

```sub score_word {
my (\$word) = @_ ;
my \$points = 0 ;
my @letters = split //, \$word ;
\$points += \$letter_points{\$_} foreach @letters ;
return \$points ;
}

You could use List::Util::sum and reduce that to:

```use List::Util qw/ sum /;

sub score_word { sum( @letter_points{ split //, \$_[ 0 ] } ) }

```  my %deny_letters = map { \$_ => 1 } split(//, \$pattern) ;
my @p = split //, \$pattern ;

Why split the same thing twice:

```  my @p = split //, \$pattern ;
my %deny_letters = map { \$_ => 1 } @p ;
