I am trying to figure out if it is possible for a hash value to reference a key value in the same hash. As a much simplified example, suppose I have the following:

use strict;
my %hash = (
            name => "foo",
            code => sub{
                        print "name: ", "foo", "\n";
                       },
            );
$hash{code}->();
_____
name: foo

"foo" is the value of the name key and is also in the code subroutine. Is it possible to have a hash refer to itself with something like

use strict;
my %hash = (
            name => "foo",
            code => sub{
                        print "name: ", $hash{name}, "\n";
                       },
            );
$hash{code}->();

Obviously this syntax does not work, but is there a way to do this?
