in thread Real life uses for closures.

Here's a closure from it ...

$sortsub = sub($$) { $spec->($_[0]->{$field}, $_[1]->{$field}) || $oldsortsub->($_[0], $_[1]) }

Lemme guess - did you just grep the code for /sub {/? :-)

    I didn't look at the source code at all - I was just referring to the usage examples in the pod.

    package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
