in reply to Golf: reverse sort /etc/passwd by UID

OK, using salva's wonderful Sort::Key, I can go five characters shorter...

perl -MSort::Key=rikeysort -e'print rikeysort{/(\d+)/;$1}<>' /etc/pass +wd

If you don't mind a spurious blank line at the end of the output, then it's easy to drop another two characters...

perl -MSort::Key=rikeysort -E'say rikeysort{/(\d+)/;$1}<>' /etc/passwd
package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
