the quadratic example in the same paper).

RPN is in MEX - introduced by cmavo "fu'a", I think. MEX has prefix
(polish), infix and postfix (reverse polish) all provided and even
mixable, with suitable cmavo. Beings with logical minds and large
short-term buffers will of course prefer either of the outer two, mere
humans will probably continue on a roll of hundreds of years and stick
with infix.
