在Perl中,如何在不使用循环的情况下过滤数组?

这里我只过滤没有子字符串的元素 world

$ cat test.pl
use strict;
use warnings;

my @arr = ('hello 1', 'hello 2', 'hello 3', 'world1', 'hello 4', 'world2');

print "@arr\n";
@arr =~ v/world/;
print "@arr\n";

$ perl test.pl
Applying pattern match (m//) to @array will act on scalar(@array) at
test.pl line 7.
Applying pattern match (m//) to @array will act on scalar(@array) at
test.pl line 7.
syntax error at test.pl line 7, near "/;"
Execution of test.pl aborted due to compilation errors.
$

我想把数组作为参数传递给一个子例程。

$ cat test.pl 
use strict;
use warnings;

my @arr = ('hello 1', 'hello 2', 'hello 3', 'world1', 'hello 4', 'world2');
my @arrf;

print "@arr\n";

foreach(@arr) {
    unless ($_ =~ /world/i) {
       push (@arrf, $_); 
    }
}
print "@arrf\n";

$ perl test.pl
hello 1 hello 2 hello 3 world1 hello 4 world2
hello 1 hello 2 hello 3 hello 4
$

我想知道是否有一种方法可以不用循环(使用一些简单的过滤)。
