Can't highlight this enough. The type of spaghetti code "goto considered harmful" was reacting to is basically impossible to create anymore, so anyone who didn't work on that type of code in the 80s or earlier probably hasn't seen it.
And thus, is applying the mantra "goto considered harmful" incorrectly. (Such as trying to avoid it in C for clean error handling, when there's no reason to avoid that.)
To try to replicate that experience, you'd have to write your entire application (including all libraries since libraries were often not a thing) as one single function in C. All of it, no matter how many tens of thousands of lines of code, all in one function. Then label every line. Then picture having GOTOs going every which way to any of the labels. For instance you'd preset the counter variable to some desired value and jump right into the middle of a loop elsewhere. Over time you'd surely accumulate special conditions within that loop to jump out. And so on. It's difficult to even imagine code like this today (or in the past 30 years).
