RE: Python to RPN converter
Just watched the talk Hy: A Lisp that transforms itself into the Python AST that you mentioned in the slides.
This made me wonder if I could translate hy to FOCAL as well?

Let's give it a try with a function that calculates the area of circle given the radius r:
Code:
(defn circle [r]
    (* pi (** r 2)))

Code:
hy 0.14.0+196.g4de18d3 using CPython(default) 2.7.10 on Darwin
=> (import [compiler [translate]])
=> (import [math [pi]])
=> (defn circle [r] (* pi (** r 2)))
=> (circle 5)
78.53981633974483
=> (translate circle.__code__)
LBL "CIRCLE"
STO 00 ; r
RDN
PI
RCL 00 ; r
2
Y↑X
*
RTN

How cool is that?

Since hy produces an AST I assume it would be easy to provide a frontend for your application.

For those of you who want to try hy.
