view release on metacpan or search on metacpan

say quicksort(@("a".."z") -> shuffle)
```

Alternatively, Sidef provides the `Block.thr` method, which creates a deprecated Perl thread, or a system fork if [forks](https://metacpan.org/pod/forks) is installed.

# Interacting with Perl modules

Sidef can interact with Perl modules in a very easy way. There is the `require` keyword which will try to load an object-oriented Perl module.

```ruby
var lwp  = require('LWP::UserAgent')
var ua   = lwp.new(show_progress => 1)
var resp = ua.get('http://example.net')

if (resp.is_success) {
    say resp.decoded_content.length
}
```

For functional Perl modules, the `frequire` keyword should be used instead to denote that the module is function-oriented.
