I've finally settled for a name for my program. It is RUR: a Python Learning Environment, or RUR-PLE for short.
Pattis's Karel the Robot was named after the author Karel Capek, who popularized the word robot in his play Rossum's Universal Robots (RUR). While RUR-PLE shares the basic RUR acronym, in this case it stands for Roberge's Used Robot. However, through the magic of Rossum's Python, you can learn how to fix it and design a better one, worthy of the name Rossum's Universal Robot.
