RPN is SO efficient if you know how to use it and its associated tools.

You see my point! Any logic system (or even language) which is heavily dependent on extra symbols or punctuation so as to remove/avoid ambiguity is higly inefficient. That's what makes RPN such a model of simple elegance. Its straightforward syntax and structure completely fulfill the idea of flawless mathematical and logic methodologies.
