Unfortunately, a lot of people were intoxicated by the Structured
Programming Kool-Aid. I've lost count of how many programs I've seen

to a function exit point. Take a sample of code from the golden era of
structured programming and there's a very good chance it will be
littered with the arrow anti-pattern.
