Untested is right. That method will DEFINITELY work with more than one object in the class. I should know - I use it in production. You are NOT "injecting"(?) closures over the current $self. Test it before you make pronouncements like that.

With the original poster's code, this test:

  my $test = Foo->new();
  my $test2 = Foo->new();
  $test->read_write("water");
  $test2->read_write("wine");
  print "test: should be water, is ", $test->read_write, "\n";
  print "test2: should be wine, is ", $test2->read_write, "\n";

gives me: 
  test: should be water, is wine
  test2: should be wine, is wine

I'm confused as to what you're saying will definitely work - the OP's code has an AUTOLOAD sub which defines a lexical $self, in which he defines a couple of anonymous subs which refer to that $self. Nothing that can't be fixed by adding a my $self into the subs, as I did in my code and as you've done in yours.
