Nice example

Be aware that if you plan to do this with a closure, B::Deparse doesn't pack any variable that the subroutine has closed over. Here is the same example that I posted above using B::Deparse:

use strict;
use warnings;
use B::Deparse;

sub makeGreeting
  {
    my $str = "Hello ";
    return sub {
      my ($name) = @_;
      print "$str $name\n";
    }
  }

my $greet = makeGreeting();
my $deparse = B::Deparse->new();
print $deparse->coderef2text($greet);

Outputs:

{
    use warnings;
    use strict 'refs';
    my($name) = @_;
    print "$str $name\n";
}

Variable $str appears in the output but its declaration is not "packed" inside the code
