In general, you're right. But...

It is possible to make subroutines un-callable from a scope, it just makes the code uglier :-) 

package Whatever;
{

  # anything outside this scope can't call this:
  my $private1 = sub {
     print "hello";
  };

  # everybody can call Whatever::foo

  sub foo {
    $private1->();  # call private method
    print " world\n";
  }
}

foo();
