Micro-optimization: the wantarray op is faster than using a temp variable.
Indeed, thanks, will fix :)
Rate var ops
var 121/s -- -19%
ops 148/s 23% --
use strictures 1;
use Benchmark qw/cmpthese/;
my $ops = sub {
if (wantarray) {
1
}
elsif (defined wantarray) {
2
}
else {
3
}
};
my $var = sub {
my $want = wantarray;
if ($want) {
1
}
elsif (defined $want) {
2
}
else {
3
}
};
cmpthese (-1 => {
ops => sub {
for (1..10000) {
$ops->();
1;
}
},
var => sub {
