in reply to OOP method usage

I get "foo" and I want to get "bar". What am I doing wrong?

You're not calling _sub1 as a method. Try  sub2 { shift()->_sub1; }

    Thank you for your reply. That works like a charm. Am I able to use $self->_sub1; in a constructor? Or is it bad programming practice ? Example: 
    sub new {
    my $class = shift;
    my $self  = {
        _txt => shift
    };
    bless $self, $class;
    $self->_sub1();
    return $self;
}

      Yes, you can call an instance method on $self in the constructor, provided you have first called bless on it (as in your example).

      is it bad programming practice ?

      No, it’s standard practice. See perlobj:

      Once we've blessed the hash referred to by $self we can start calling methods on it. This is useful if you want to put object initialization in its own separate method: 

        sub new {
      my $class = shift;

      my $self = {};
      bless $self, $class;

      $self->_initialize();

      return $self;
  }
