I remember back in the 70s in college the great debate was whether the HP-35 calculator with RPN was better or worse than the TI SR-50 with infix notation.

My conclusion was that RPN required less to remember than infix, and with a calculator you had to be very careful to not mess up where you were in punching buttons.

But for a tty, infix wins every time. Like no book publisher ever writes math equations with RPN, unless they are writing about Forth or Lithp or some intermediate code.

I should have known, however, that my remark about RPN not being human would flush out the 3 people for whom it is!
