<p>Benchmarks are interesting:
</p>
<c>
use strict;
use warnings;
use Set::Scalar;
use Benchmark qw(cmpthese);
my @array = qw(a b c d e f g h i j k l m n o p q r s t u v w x y z);
cmpthese
(-1,
{
'GF' => sub {my %hash; @hash{@array} = (1) x @array;},
'map' => sub {my %hash = map {($_, 1)} @array;},
'map++' => sub {my %hash; map {$hash{$_}++} @array;},
'set' => sub {my $set = Set::Scalar->new(@array);},
}
);
</c>
<p>Prints:</p>
<c>
Rate set map map++ GF
set 2203/s -- -84% -91% -92%
