In Perl 6 this could almost look the same: for @numbers -> $number { next unless $number > 10; next unless $number % 2; work($number); } Although personally, I wouldn't write it like that: I would probably write it as: for @numbers.grep( { $_ > 10 && $_ % 2 } ) -> $number { work($number) } or use the postfix notation: work($_) for @numbers.grep( { $_ > 10 && $_ % 2 } ); If you want to spread this out over multiple CPUs and you don't care about the order in which the work is done, you only need to add the `.race` method: for @numbers.grep( { $_ > 10 && $_ % 2 } ).race -> $number { work($number) } More info: https://docs.perl6.org/routine/race https://docs.perl6.org/routine/race
