The rpncalc package adds an interactive Reverse Polish Notation (RPN)
interpreter to Python. This interpreter allows the use of Python as
an RPN calculator. You can easily switch between the RPN interpreter
and the standard Python interpreter.

The ratfun module provides classes for defining polynomial and rational
function (ratio of two polynomials) objects. These objects can be used
in arithmetic expressions and evaluated at a particular point.

This is somewhat in between a bug report and a feature request.
I was using the new string.Template class and I have run into a

I do not understand why '%s' % val was used
