    <p>I think you're extrapolating from your particular use case.</p>
    <p>I would say most people use $0 for private variables/resources.
      In this case the very point is that those are not accessible from
      outside. If I do want to make things accessible from the outside,
      I wouldn't use $0 in the first place...<br>

            <p>I have to say I quite like the "$$" idea as well,
              assuming that we can take the risk of breaking a few
              patches (if any).</p>
            <p>I don't think it's a good idea to add a new object just
              for this functionality. For me this would create
              unnecessary complexity (you have to learn yet another
              object).<br>

                  <div>I'm not sure either. To me, both $0 and $1 etc.
                    can be used to identify an instance of an
                    abstraction. <br>
                  </div>
                  <div>IMO $0 is the quick way, but has the limitation
                    to make it (nearly) impossible to access members
                    from the outside.</div>
                  <div>That's why it often happened to me to rename an
                    instance [myAbs] to e.g [myAbs myabs1], then to
                    replace $0 in [myAbs] with $1, so I can easily
                    access [myAbs]'s members from the parent - from
                    anywhere in fact (Actually, nowadays I tend to use
                    as few $0 as possible).<br>
                  </div>
                  <div>If we could use $0 in messages, then the last

            <p>I agree that if we get the "$$" syntax, then it makes
              more sense to use "$$0" for the $0 argument! Without the
              "$$" syntax, I wouldn't see the problem...</p>
            <p>One downside of using "$$0" is that it wouldn't be
              compatible with Pd-L2Ork / PurrData.If they have already
              diverged significantly, we probably don't have to care,
              but otherwise...</p>
