Hah, another old benchmark i had laying around #!/usr/bin/perl --
use strict;
use warnings;
use Benchmark 'cmpthese';
my @small = 1;
cmpthese( 500_000, {
'__' => sub {
for my $line ( @small ){
next if $line !~ /\s+(-?\d+\.\d+)\s+(-?\d+\.\d+)/;
}
return;
},
'/_'.$].'_/' => eval '
sub {
for my $line ( @small ){
next if $line !~ /'.
qr{\s+(-?\d+\.\d+)\s+(-?\d+\.\d+)} # 5.12.2 (?-xism:
# 5.14.1 (?^:
.'/;
}
return;
}
',
'qr' => sub {
my $re = qr{\s+(-?\d+\.\d+)\s+(-?\d+\.\d+)};
for my $line ( @small ){
next if $line !~ $re;
}
return;
},
'/qr/' => sub {
my $re = qr{\s+(-?\d+\.\d+)\s+(-?\d+\.\d+)};
for my $line ( @small ){
next if $line !~ /$re/;
}
return;
},

'qr,//o' => do {
our $gre = qr{\s+(-?\d+\.\d+)\s+(-?\d+\.\d+)};
sub {
for my $line ( @small ){
next if $line !~ /$gre/;
}
return;
};
},
});
