"The Python programmer said he had downloaded BASIC, and was experimenting with it. “But what is this GOTO stuff?” Never. Never ever ask that. One negative effect of asking that question is the horror of finding out that you use GOTO more than BASIC programmers; but because they are everywhere in your life, you have developed a blind spot to them. (Hint: do you use if?) In fact, as I showed him, every control structure in Python is an instance of GOTO."
