"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."
A nice analogy, but I would argue that as monads are at a higher level of abstraction than nullables it's more akin to "but what is this if stuff?" It is the f(v) if v else None which is analogous to GOTO, not the simpler and more direct v >>= f.
