Re: How can I access object data in a user defined sort cmp function?

in reply to How can I access object data in a user defined sort cmp function?

(I came to the conclusion Guido was right about whitespace)

using global... I mean, local our variables. Just like $a and $b.

use strict;
use warnings;

sub sort_aux {
    our $self;
    $a <=> $b;
}

sub hash_ref_keys_by_value {
    local our $self = shift;
    my @keys = sort by_value
      keys %{ $self->{hash_ref} };
}
