Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Is there a way to create a reference to a subroutine from a package being used? For instance, if I had a package called Subs, which had a subroutine called new, I try to do this: 

use Subs;
my %menu = (
    n => \&Subs->new;
);
. . .
$menu{n}->();

This doesn't work, is there a way to pull it off?

    Nevermind I figured it out: 

    my %menu = (
    n => \&Subs::new;
);

    That was dumb.

      Except if that's a method call, that won't work, because you're not passing the name of the class as the first parameter. Try this: 
      my %menu = (
  n => sub { Subs->new },
);
