Following up on a sharp observation of tye's in CB, I decided to check whether some of your sorts were in fact no-ops. Here's what I benchmarked, and the results:
srand 0;
my @fixture = map 'foo' . int( rand 1000 ). '.tla', 1..5000;
use Benchmark 'cmpthese';
cmpthese( -1,
{
naive => sub { ( naive( @fixture ) )[ 0 ] },
orcish => sub { ( orcish( @fixture ) )[ 0 ] },
schwartzian => sub { ( schwartzian( @fixture ) )[ 0 ] },
guttros => sub { ( guttros( @fixture ) )[ 0 ] },
}
);
__END__
Rate naive orcish schwartzian guttros
naive 3.05/s -- -65% -76% -87%
orcish 8.74/s 186% -- -31% -61%
schwartzian 12.7/s 317% 46% -- -44%
guttros 22.6/s 642% 159% 78% --
Note that the subs that are benchmarked return the first element of the sorted array.
