Technically none of the examples from Sort::MultipleFields employ closures; they just use anonymous functions. Closures "close over" a variable.

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.
