In this clip, Martin Fowler shares a timeless story from the early days of Smalltalk to show why intent—not line count—is the real guide for how long a function should be. He argues that when there's a gap between what the code does and what it says, it's a sign to extract a function.
Uncle Bob, on the other hand, recommends keeping functions short—ideally 5 to 10 lines—as a clear, repeatable rule.
So who's right? The flexible, intent-driven approach or the clear-cut metric?
In reality, both serve as diagnostic tools. A long function isn’t always bad, and short functions aren’t always good. But when multiple symptoms—like length and lack of clarity—start piling up, that's when you should investigate.
